A train of length 100m is crossing a bridge 200m in length, at the speed of 15 m/s. What is the time taken by the train to cross the bridge?
Answer: 20 sec
Explanation
Total distance = Length of train + Length of bridge = 100 m + 200 m = 300 m
Speed = 15 m/s
Time = Distance / Speed = 300 / 15 = 20 seconds
