Answer:

7.5 mph

Explanation:

Given :

Distance traveled in miles = 10 miles

Time taken = 1 hour 20 minutes

In other to express average speed on terms of miles per hour :

Time in hour = 80 / 60 = 1.333333 hours

Average speed = Distance traveled / time taken

Distance = 10 miles / 1.33333 hours

Distance = 7.5 miles per hour
