Kenneth ran a marathon (26.2 miles) in 5.5 hours. What was Kenneth's average speed? (Round your answer to the nearest tenth.) 0.2 mph 4.8 mph 5.5 mph 144.1 mph

4.8 mph

Explanation:

From the question,

Average speed = total distance/total time

V = d/t Equation 1

Where d = distance, t = time

Given: d = 26.2 miles, t = 5.5 hours.

Substitute these values into equation 1

V = 26.2/5.5

V = 4.76 mph

V ≈ 4.8 mph
