Distance formula 2

Two vechicles cover the same distance at the rate of 15 kmph and 16 kmph respectively. Find the distance when one takes 16 min longer than the other.

Solution:

Let distance travelled be p km.

Time taken by first runner: p/15 hrs.

Time taken by the second runner: p/16 hrs.

Given that p/15 – p/16 = 16/60.

Solving we get

p = 64 km.

Shorter method:

Distance = (product of speeds x difference in time to cover distance) / difference of speeds.
