A truck driver must complete a 180-mile trip in 4 hours. If he averages 50 miles an hour for the first three hours of his trip, how fast must he travel in the final hour?

A 30 mph
B 45 mph
C 35 mph
D 40 mph

Correct Answer: 30 mph

d = s x t = 50 x 3 = 150 now distance left = 180 - 150 = 30 thus he need s to travel 30 miles in 4th hour thus his speed should be 30 miles per hour
