Final answer:
The athlete ran for approximately 0.4615 hours, or about 27.69 minutes, to cover 3 miles at a speed of 6.5 miles per hour.
Step-by-step explanation:
To calculate the time it takes for the athlete to run 3 miles at a speed of 6.5 miles per hour, we use the formula for time, which is time = distance/speed. In this case, the distance is 3 miles and the speed is 6.5 miles per hour. Thus, the time taken by the athlete to run 3 miles is calculated as follows:
Time = Distance / Speed
Time = 3 miles / 6.5 miles per hour = 0.4615 hours
The athlete ran for approximately 0.4615 hours, which is about 27.69 minutes (since 1 hour = 60 minutes, simply multiply 0.4615 hours by 60).
