worefa, no idea!
ReplyDeleteAbeg Stella tell us jare, I wan hear from u
DeleteIt's a round pool na so where the edges want come from.
ReplyDeleteLagos people know how to organise party but don't know how to catch there fun!everybody they form oga and madam,nobody one talk to each others ,y hiding and y is th essence of the party!
ReplyDeleteI think we need to see more of d party pictures. .... PH still topping it.
DeleteHmmmmmm
ReplyDeleteMy. Brain is on temporary retreat.....!
ReplyDeleteThe dog should remain where it is! Would not get caught as the tiger cannot swim.
ReplyDeleteI jump am pass.
ReplyDeleteHian
ReplyDeleteThis Lagos party pictures dey vex me jare...Hetty, what happened to the other pictures? There were 3 square meals that night now: fried/jollof rice, semo/eba and sumptuous elusive with vegetables so why these boring Cruz pictures? I can't even see myself more than once after I've planned to get pictures from here cos my camera wasn't so clear and d photographer that took my pictures was no where to be found after the event. And now our group has been dissolved!!!!!! Please we need more pictures ooooooooooo.
ReplyDelete******egusi with vegetables
DeleteD pics dey vex me too . Can't even see stella banner ......
DeleteJust negodu...

ReplyDeleteBe right beack with the answer
*faithful BV enemuwe thelma*
Hian. See question
ReplyDeleteI no fit abeg
ReplyDeleteMe i don't know!
ReplyDeleteHehehehe I no even read am finish. Waiting for IHN
ReplyDeleteSdvcfvdbndfkfjdcxascvbndsnmdflcfdxvbd
ReplyDeleteLol I no know
ReplyDeletethe dog should use his sixth sense to know danger is around the corner
ReplyDeleteHmmmm Stella this question na wa.... since when does a circular swimming pool have an edge?
ReplyDeleteOk stella now ure pushing ur luck...ratio kwa
ReplyDeleteKo si solution!
ReplyDeleteHian
ReplyDeleteStella may God forgive you. The swimming pool no get water inside
ReplyDeleteCircles do not have edges
ReplyDeleteThis is physics....
ReplyDeleteDistance=velocity * time
Acceleration= velocity * distance
#mumsy draws my ear and says "Aboy i thought you are an Engineering student;why are you embarrassing yourself like this nna....
Abeg sdker's make una use that formula above finish am una self jare..i don try!!

There is no tiger that cannot swim. Tigers swim by far faster than any human.
ReplyDelete180 degrees : 90 degrees
ReplyDelete(tiger) (dog)
If d dog swims the opposite direction to the tiger (radius 90 degrees), the tiger will have to go 180 degrees (semi circle) to catch d dog
Represent the Tiger as T
ReplyDeleteRepresent the Dog as D
The swimming pool is it rectangular or circular, ehnnn Stella Nwunye Korkus?
Where is d swimming pool located?
Germany or Nigeria?
*fans sef*
*yawns*
Brb
Lemme knw if anyone on ds blog has gotten d ansa.
Hehehehe
A tiger can swim.thank me later...lol
ReplyDeleteThere are two things involved; either this puzzle is completely flawed and unsolvable given that we don't know if the swimming speed of the dog equates the running speed of the tiger(or if the tiger can actually run faster to compensate for more distance in less time) OR I will 'attempt' to suggest my answer based on several assumptions on info not given.
ReplyDeleteApproach 1; Imagine the dog is in the middle of the circular pool (you can draw it out if you want). where is the tiger relative to the dog? Well, it doesn't really matter since its a circular pool, regardless of what "edge" the tiger is standing, all still join, it will be at equidistant to the dog.
Approach 2; the distance the dog will swim to any edge will also be the radius (R) of the pool. Now assuming the dog will always swim in a direction directly away from the tiger, it means any direction the tiger chooses to pursue with will be equal to 'half the circumference' of the pool which is 'πR'.
Approach 3; it means the Tiger has πR distance to cover, while the dog has R to cover. which means the Tiger has approximately 3 times more distance than the dog. since 3 is the rough value of π.
Approach 4; What is the maximum ratio of running/swimming speed? This is where one runs into trouble trying to solve this. Speed is a function of the distance covered divided by the time taken. To correctly answer this, how about we look for the minimum ratio of speed (all things being equal)needed for the tiger to catch up and eat the dog? Firstly then, Speed=Distance/time. if tiger catches up with the dog, we must "assume" they arrive at the same time on shore. meaning time for both is same=t. Therefore swimming speed for dog=R/t, running speed for Tiger=πR/t or 3R/t. The ratio of the two speed then becomes 3, assuming time of arrival (t) on shore has to be same.
Approach 5; Since the puzzle says the dog swims ashore before the Tiger gets to it, it means the tiger must operate at a speed less than 3 times that of the dog. it means the maximum ratio is 2 for the dog to escape! and the strategy is to swim away in a direction opposite the tiger and gerrout of dia.
I don't know if you're right or wrong but I found it quite interesting reading your response.
DeleteRound swimming pool?
ReplyDeleteDistance
Velocity and others all join.
As far as the tiger can't swim, it can't the dog
ReplyDeleteLet the dog swim in the opposite direction to the tiger.
ReplyDeleteAnd once the Tiger starts running round the circumference of the swimming pool to where the dog is headed, the dog knowing the Tiger can't jump into the water, should make a sharp spiral turn to the point the Tiger took off from.
Let the dog maintain a spiral radius of p=3.146
And it will scale the edge of the swimming pool and take off.
The floor will be wet from the water he shed and Tigers don't allow wet claws, so the Tiger is gonna watch the dog run away.
Una no go like to see me as i dey move my cursor up and down; if i read comments na so i go go back to read the story to see if i fit decode the answer. Abeg! Quantitative reasoning no start for my primary school days so how i wan answer this kind question. Stella over to you oooooooo chei!
ReplyDeleteGracie now GracieSDKblog'sCuteness
The only thing I know is that a circle I s 360° .
ReplyDeleteThe maximum ratio is one. Since the dog is at the center of the pool. The shortest distance will be the radius. The shortest distance for the tiger to the dog is also the same as the radius. But when the dog swims, the distance it swims is the radius but not for the tiger. At the same speed the tiger swims one forth of the circumference of the pool which is more than the radius, letting the dog get away
ReplyDeleteDog and water? Mba
