Patrick took a trip on his motorcycle. He drove at a steady speed of 50 mph, and the trip took him 3 hours. How long would the trip have taken if his speed was 40 mph?

A. 3.75 hr

B. 4.00 hr

C. 4.25 hr

D. 4.45 hr

Solution

A. If Patrick traveled at 50 mph for 3 hours, the trip was 3(50) or 150 miles. Recall the formula D = rt, whereD = distance, r = rate, and t = time. Substitute what you know. D = 150 miles; r = 40. 150 = 40t. Solve for t. t= 3.75 hours.
