hours. At that speed, how long would it take Fred to run 8.5 miles?

Answer 1

To find out how long it would take Fred to run 8.5 miles, we need to determine the running speed per hour.

First, we need to find the time it took Fred to run 6.25 miles: 1 1/4 hours = 1.25 hours.

Next, we need to find Fred's speed in miles per hour: 6.25 miles / 1.25 hours = 5 miles per hour.

Finally, we need to calculate the time it would take Fred to run 8.5 miles: 8.5 miles / 5 miles per hour = 1.7 hours.

Therefore, it would take Fred 1.7 hours to run 8.5 miles.
