Question

A 300 m long train cross a 1200 m long bridge with a uniform speed 54k/h calculator the time taken by the train to cross the bridgh

Answer 1

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

Answer 2

the time to cover the bridge is 100 seconds
