Question
A train moving at 15 m/sec passes a cyclist who is traveling in the same direction as the train, and it takes 20 seconds for the train to completely pass the cyclist. Determine how much time it will take for the train to pass the same cyclist if the cyclist moves in the opposite direction at a speed of 5 m/sec, given that the length of the cycle is 1 meter.
