If you would like to know the average speed of the car in miles per hour, you can calculate this using the following steps:

120 miles ... 1 hour and 45 minutes = 105 minutes
x miles = ? ... 1 hour = 60 minutes

120 * 60 = x * 105
x = 120 * 60 / 105
x = 68.57 miles

The correct result would be 68.57 miles per hour.
