Maybe they aren't looking for a specific amount of time, like 2 hours and 3 minutes. Maybe the answer should be expressed in terms of the variables you have?
His average speed would be:
Then to figure out how long to run 20 miles, you divide 20 by the average:
I believe the above equation is the answer.
Let's say he run 8 miles in 1 hour and then 10 files in 2 hours. His average speed is 6 hours (18/3), so it should take 3 1/3 hours.
