If you can run 750 meters in 1 minute, 25 seconds, how fast is that in miles per hour
The Correct Answer and Explanation is:
Correct Answer:
19.8 miles per hour (rounded to one decimal place)
Explanation:
To determine how fast 750 meters in 1 minute and 25 seconds is in miles per hour, follow these steps:
Step 1: Convert the time into seconds
1 minute = 60 seconds
So, 1 minute and 25 seconds = 60 + 25 = 85 seconds
Step 2: Convert meters to miles
There are 1,609.34 meters in 1 mile.
So, 750 meters = 750 ÷ 1,609.34 = 0.466 miles (approximately)
Step 3: Convert time from seconds to hours
There are 3,600 seconds in an hour.
So, 85 seconds = 85 ÷ 3,600 = 0.02361 hours (approximately)
Step 4: Calculate speed in miles per hour
Speed = Distance ÷ Time
Speed = 0.466 miles ÷ 0.02361 hours ≈ 19.73 miles per hour
Rounded to one decimal place, the speed is 19.8 miles per hour.
Understanding the Result:
This speed means that if you kept running at the same pace for an entire hour, you would cover about 19.8 miles. This is quite fast and suggests elite-level sprinting or middle-distance running ability. For context, professional marathon runners average speeds around 12 to 13 miles per hour, while sprinters can briefly exceed 20 miles per hour but not for long distances.
This type of unit conversion is useful in comparing performance across different systems of measurement or for understanding fitness and athletic benchmarks. It also demonstrates how mathematical reasoning connects with real-life scenarios like sports and physical education.
