Question

A boat moves 15.0 km across a lake in 30.0 min. what was the average speed of the boat in kilometers per hours?

Answer 1

To work out the average speed you would have to use the formula

AS = 15.0 ÷ 30.0 = 0.5 which is distance divided by time.

The you would do 0.5 x 60 = 30 (60 minutes = 1 hour)

So the average speed would be 30.0 km/h.
