A car travels 98 miles in 1 hour and 45 minutes. what is the average speed?

Firstly let us get the time down to minutes from hours. Then the calculation will become easy.

1 hour and 45 minutes = (60 + 45) minutes

= 105 minutes

So

The distance traveled by the car in 105 minutes = 98 miles

Then

The distance traveled by the car in 60 minutes = (98/105) * 60 miles

= 5880/105 miles

= 56 miles

So the average speed of the car as can be seen from the above deduction is 56 miles per hour.
