Question

1. A car travels 46.7km in 2hours and 23 minutes. What is the average speed of thecar?

Answer 1

First, we have to transform 23 minutes into hours, knowing that 1 hour is equivalent to 60 minutes.

`23\min \cdot(1h)/(60\min )=0.38h`

Then, we add this time to 2 hours to get 2.38 hours in total.

Now, we divide the distance traveled by the time spent to get the average speed.

Therefore, the average speed is 19.62 km/hr.
