While finding the speed of the B, why we are using the 92m only instead of 100m?

Out of 100m he ran 8m so we deduct 8m from 100m then we get 92m to obtain B Speed we should caluclate B Speed by using 92m instead of 100m. I hope you understand. !

We should understand the ques properly. Its in the ques that b is 8m forward than a in 100m race, am I right?

Here first we can find the losers time, secondly we can find losers distance[since losers distance=winners distance- (start distance+beat distance) ] and later we can find the speed of B[since speed=distance/time]. Which is the final answer.
Is this not the correct procedure. Please tell me if it is.

Why Time taken by B to cover 92 m = (72 + 8) = 80 sec. comes?
Can any one explain ?

@Baburaj:
Because A is taking 72sec to run 100m and beats B by 8sec.
that means still B needs 8sec to complete 100m.
therefore time taken by B to complete 92m is 72+8=80sec.

How did you get A's speed ? I dint understand. Please explain.

How A's speed is found ?

@anamika & sayed
A's speed is in kmph. to make it in m/s, 5 is multiplied with 1000/(60X60).
Hence, 5X5/18=25/18
m/sec
Time taken by B to cover 92 m = (72 + 8) = 80 sec.
