In a circular race of 750 m, X and Y start from the same point and at the same time with speeds of 9 km/h and 13.5 km/h, respectively. If they are running in the same direction, when will they meet again for the first time on the track?
Show answer & explanation

Explanation
The correct answer is option 4 i.e. 600 seconds.
Time = Distance/Relative speed
Relative speed in same direction = S1 - S2
Time = = 750/1.25 = 600 seconds
