Question

David's mother flew on a plane for a business trip. The plane averaged 500 miles per hour for the entire 1,250-mile flight. The plane was 45 minutes on the runway. How many hours did David's mother spend on the plane?

Answer 1

3.25 hours

Explanation:

1250 miles / (500 miles/hour) = 2.5 hours

45 minutes × (1 hour)/(60 minutes) = 0.75 hours

2.5 hours + 0.75 hours = 3.25 hours

Answer: 3.25 hours
