Question

A 50m train passes over 250m long bridge at a velocity of 60km/h. How long will it take to pass, completyly over the bridge

Answer 1

Given,
Length of train = 50m
Length of bridge = 250m

Velocity of train= 60 kmph = 60×(5/18) mps = (50/3) mps

[°•° 1 kmph = (5/18) imps]

Distance Covered = (50 + 250)m = 300m

Required time= Distance covered/Velocity
•°• Required time= 300/(50/3)
= (300×3)/50
= 900/50
= 90/5
= 18 sec

•°• Train takes 18 seconds to cross the bridge completely.
