Question

Jaidev takes 2 3/5 mins to walk once around a circular park. If he maintains the same speed, then how many rounds will he make in 9 1/10mins?

Answer 1

Answer:

time taken by jaidev to make 1 round=2 3/5 =13/5minutes

total time =9  1/10 =91/10minutes

let no of rounds = x

then,

X x 13/5  = 91/10

x =91/10 /13/5

x=91/10 x 5/13

x =91 /26

x=7/2

x=3 1/2
