A truck completed a journey of 48 kilometres at an average speed of 64 km/h.
How many minutes did the journey take ?

The average speed of the truck is 64 km/h
Therefore:
64 / 60 = 1.06 km per minute
The truck is travelling at a speed of 1.06 km per minute.
48 / 1.06 = 45.28 minutes
Answer:
The journey will take 45.28 minutes
