A train 120 m long passes a bridge in 18 seconds moving at a speed of 60 km/h. Find out the length of the bridge.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 180 m
Let the length of the bridge = l meter
We know that
Length of the train + length of the bridge = relative speed × time covered
120 + l = 60 × (5/18) × 18
120 + l = 300
l = 300 - 120 = 180 m
