A train leaves at 13.23 and arrives at its destination at 14.05. If the train travelled 31 km, what was it's average speed in km/h? Give your answer rounded to 1 dp.
It took 42 minutes from takeoff to get to its destination, so when you divide 31/ 42 (42 representing the time and 31 km representing the distance), you get 0.738 km/h
