P and Q start running in opposite directions on a circular track from the same point. If their speeds are 10 m/s and 8 m/s, respectively, then after what time will they meet if the length of the track is 1620 m?

Question

Accepted Answer

P and Q start running in opposite directions on a circular track of length 1620 m. Their speeds are 10 m/s and 8 m/s respectively. When two runners run in opposite directions, their relative speed is the sum of their speeds.

Relative speed = 10 + 8 = 18 m/s

They will meet when the sum of the distances they cover equals the length of the track (1620 m).

Time taken to meet = Distance / Relative speed = 1620 / 18 = 90 seconds.

Hence, they will meet after 90 seconds.
