Question

A commuter train travels 50 kilometers in 43 minutesWhat is speed in kilometers per hour?

Answer 1

70.42 kilometers.

Explanation:

43 minutes/60 minutes (1 hour is 60 minutes) = 0.71 hours.

Now we set up a problem here.

50 kilometers/0.71 hours = x kilometers/1 hour

We multiply out 1 hour and cancel out from both sides.

50/0.71 kilometers = 70.42 kilometers.

Therefore, the train was traveling at 70.42 kilometers per hour.
