Car A travels at 60 mph for 3 hours. Car B travels the same distance as Car A but takes 4 hours. What is Car B's average speed?
✓ Correct Answer: Option B
Car A's distance = Speed * Time = 60 mph * 3 hours = 180 miles. Car B travels the same distance (180 miles) in 4 hours. Car B's average speed = Distance / Time = 180 miles / 4 hours = 45 mph.
