Question

a 150 m long train is moving with a uniform velocity of 45 kmph the taken by the train to cross a bridge of length 850 m is​

Answer 1

Total Distance = 150 + 850 = 1000 m = 1 Km

Velocity, v = 45 kmph

velocity = distance( or displacement) / time

time = 1 / 45 hr

time = 0.0222 hr × 60 min

time = 1.33 min
