Question

A car travels 240 kilometres in 3 hours and 20 minutes

Calculate the average speed, in km/h, of the car

Answer 1

Around 72.72 km

Explanation:

20 minutes is 1/3 of 1 hour so in decimals it would be 0.3333

so 3.3 hours.

240 km divided by 3.3 hours is equal to 72.72727272

If you round it it would be around 72.72 km per hour

hope this helps :)
