A train 360 m long is running at a speed of 45 km/hr. In what time will it pass a bridge 140 m long?

Q: A train 360 m long is running at a speed of 45 km/hr. In what time will it pass a bridge 140 m long?

Given Train length = 360 m Bridge length = 140 m Speed = 45 km/h Compute Speed = 45 × (5/18) = 12.5 m/sTotal distance = 360 + 140 = 500 mTime = 500 / 12.5 = 40 s

Difficulty: Easy

38 s
40 s
42 s
44 s

Correct Answer: 40 s

Explanation:

Given

Train length = 360 m
Bridge length = 140 m
Speed = 45 km/h

Compute
Speed = 45 × (5/18) = 12.5 m/sTotal distance = 360 + 140 = 500 mTime = 500 / 12.5 = 40 s
