Question

Ex:
Two runners cover the same distance at the rate of 15
km and 16 km per hour respectively. Find the distance
travelled when one takes 16 minutes longer than the
other. ​

Answer 1

Step-by-step explanation:

64 km

Let x be the distance and t time taken by 2nd cyclist in hour

Since one cyclist takes 16 min more

x/15 = t + 16/60 ---(1)

x/16 = t ---(2)

(1) - (2)

x/15 - x/16 = 16/60

x/(15*16) = 16/60

x = 15*16*16/60

=64km
