Question

A 50m long train passes over a 250m long bridge at a velocity of 60km/h .How long will it take to pass completely over the bridge?
​

Answer 1

Convert km/h to m/s - km/h divided by 3,6=m/s so 30 km/h is about 8,33 m/s. Now divide 300 m by the speed of the train - 300/8,33= 36 - so it takes the train 36 seconds to pass the bridge completely.
