Final answer:
The athlete can run approximately 9.6 miles in one hour.
Step-by-step explanation:
To find out how far an athlete can run in one hour if they run 9 miles in 56.25 minutes, we can use the formula:
Distance = Speed × Time
Since the athlete is running 9 miles in 56.25 minutes, we can calculate their speed: × = ÷
Speed = Distance ÷ Time
Speed = 9 miles ÷ 56.25 minutes
Speed = 0.16 miles per minute
To find out how far the athlete can run in one hour, we need to convert the speed to miles per hour:
Speed = 0.16 miles per minute × 60 minutes per hour
Speed = 9.6 miles per hour
Therefore, the athlete can run approximately 9.6 miles in one hour.
