Question

How much time will a 620 m long train take to cross platform 800 m long if it is moving at a speed of 72km/hr?

Answer 1

As speed is 72 x 1000/3600 = 72000/3600=20m/s
speed = distance /time so time =distance /speed here distance is 800m so 800/20= 40second is the answer........Hope it's helpful ________Mark as Brainliest
