Circular track: Both are in same direction. A = 3m/sec, B = 1 m/sec. Circumference of track = 100m.

What is the time taken by A & B to reach starting point for first time?

B moves at 1 m/sec. The track is 100 m in length. $t = \dfrac{100 \, m}{1 \, m/sec} = 100 \, sec$ for B to complete one lap on the track. In that time, A will complete 3 laps.
