The average speed of stefan is 0.57 miles per hour.
Given, In heavy traffic, Stefan covered just 25 miles in 1 hour and 8 minutes on his way to work.
He left work early to beat the rush hour and made it home in 32 minutes using the same route.
speed of steven in heavy traffic = distance/ time
distance = 25 miles
time = 1 hour and 8 minutes = 68 minutes
therefore, speed = 25/68 = 0.36 miles per hour.
speed of steven while returning back to home.
distance = 25 miles
time = 32 minutes.
speed = 25/32 = 0.78 miles per hour.
average speed = 0.36 ₊ 0.78/2
= 1.14/2
= 0.57 miles per hour.
hence we get the average speed as 0.57 miles.
