Question

A train 110m long is running at 108km/hr. It crosses a bridge in 13 seconds. Find the length of the bridge.

Answer 1

Answer:

Speed of Train (v) = 72 km/h = 20 m/s

Distance (s) = 110 m + 132 m = 242 m

Time (t) = ?

Formula: v = s / t → t = s / v = 242 m / 20 m/s = 12.1 s

It will take roughly 12 seconds for the train to cross the bridge.
