What is the correct equation to ensure the treadmill MPH displayed is accurate?

• A. Belt length (inches) x number of revolutions/min divided by 360
• B. Belt length (inches) x number of revolutions/min divided by 1056
• C. Belt length (inches) x 1056 divided by number of revolutions/min
• D. Belt length (inches) x 1000 divided by number of revolutions/min

Answer: (B)

The correct equation to ensure the treadmill MPH displayed is accurate involves calculating the treadmill's speed based on the belt length and the number of revolutions per minute (RPM). Option B, which states "Belt length (inches) x number of revolutions/min divided by 1056," is the correct choice because it properly correlates these variables to convert the belt movement into a speed measurement in miles per hour. To break down this equation, the belt length provides the distance covered per revolution, and when multiplied by the number of revolutions per minute, it gives a total distance traveled in inches per minute. The division by 1056 is crucial for converting this measurement into miles per hour: - There are 63,360 inches in a mile (5280 feet per mile x 12 inches per foot). - Since there are 60 minutes in an hour, the formula factors in these conversions, and thus, dividing by 1056 accounts for the necessary scaling to achieve the correct MPH. This formula aligns with standard practices for speed calculation on treadmills, ensuring that the readings are accurate for exercise performance assessment.
