Question

Two runners cover the same distance at
the rate of 15 km and 16 km per hour
respectively. The distance travelled when
one takes 16 min longer than the other is​

Answer 1

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

Answer 2

Answer. 16/60 = 4/15 hours.
