Question

A 200m long train crosses a 400m bridge with a velocity of 36km per hour.find the time taken by the train to cross the bridge

Answer 1

We convert the speed to meters per second :

We do this as follows :

36 × 5/18 = 10m/s

The total distance covered by the train is :

Length of the train + length of the bridge

This is :

400 + 200 = 600m

Time = Distance /speed

600/10 = 60 Seconds

This is equivalent to 1 minute
