Question

A takes 11.5 s to cover 100 m and b takes 12.5 s to finish 100m,then how many meters a infont of b

Answer 1

hey mate

here is your answer

the speed of A=100/11.5 m/s

the speed of B=100/12.5 m/s

A is faster than B

when A was at finishing point ,
then then was 11.5 s.

therefore ,the distance traveled by B in 11.5=100/12.5*11.5

=8*11.5

=92 m

therefore, the difference between them =100 -92 m

=8m (answer)
