Description: Suniti and Bhoomi start a race from the same position and at 08:05:00 a.m. in same direction along a circular track of 4 km long. The speed of Suniti and Bhoomi was 36 km/hr and 45 km/hr respectively. The time at which both will meet again at the starting point is:

Solution

Their relative speed = 45-36 = 9km/hr as they are moving in the same direction.
Time taken to cover 4kms with this relative speed = $$\frac{4}{9}hrs\ =\ \frac{4}{9}\times\ 60\ \min\ =\ \frac{80}{3}\min$$
This can be further written as 26 mins and 40 seconds.
They started at 8 : 05 am so they will meet at 8 : 31 : 40 am.
