Question

A train traveled a distance of 255 kilometers. If the trip took 4 hours, what was the train's average speed in meters per second? Give your answer to the nearest whole unit.

Answer 1

255 km = 255,000 m
4 hrs = 14,400 sec
255,000 m/14,400 sec = 17.7083 --> 18 m/sec

average speed - 18 m/sec
