Question

A 300m long train cross 1200m long bridge with a uniform speed of 54km/hr. Calculate the time taken to cross the bridge

Answer 1

Answer:

Explanation:

Length of train = 300 m

length of bridge = 1200 m

speed of train = 54 km/h = 54 × 1000/3600 = 54 × 5/18 = 15 m/s

We know,

time taken by train to cross the bridge = (length of bridge + length of train)/speed of train

= (1200 + 300)/15 = 1500/15 = 100 sec

Hence, time taken by train to cross the bridge is 100 sec
