Solution: We have,

The racer moves at miles per hour.

The racer expends energy at a rate of calories per hour.

So, energy expended while moving miles calories.

Now, energy expended while moving mile calories.

So, energy expended while moving miles calories.

Hence, calories of energy is required to complete a marathon race miles at this pace.
