A train travelling at 90 km/h passes a car sitting at a railway crossing. It took 45 s for the train to pass. How long was the train, in metres.
- Thanks!
90 km/h x 1,000 m ==90,000 m/h
90,000 / 3,600 seconds ==25 m / second
25 m/s x 45 s ==1,125 meters - length of the train.
Thanks a lot! Much appreciated.
