a train 360 metre long runs with a speed of 45 km / hr . what time will it take to pass a platform of 140 metre long ?
speed = 45 km / hr = 45 × 5 / 18 = 25 / 2 m / s distance travelled = ( speed x time ) time = ( distance travelled / speed ) distance travelled = length of the train + length of the platform = 360 + 140 = 500 m = 500 / 25 / 2 = 40 sec answer : c
multiply(divide(divide(add(360, 140), const_1000), 45), const_3600)
