Question

Hi I need help with this homework this is not a test

Answer 1

To determine the speed, we will divide the total distance covered by the total time spent traveling.

`speed=distance/ time`
`speed=412.5miles/7.5hrs`

Note that 7 1/2 is just equal to 7.5.

Divide the numbers above and the answer is:

`speed=55miles\text{ }per\text{ }hour`

Answer:

Ivan was driving at a constant speed of 55 miles per hour.
