How would you calculate miles per hour from distance in feet?

• A. MPH = Distance (ft) ÷ (60 x minutes)
• B. MPH = Distance (ft) ÷ (88 x minutes)
• C. MPH = Distance (ft) ÷ (120 x minutes)
• D. MPH = Distance (ft) x (88 x minutes)

Answer: (B)

To calculate miles per hour (MPH) from a distance given in feet, it is essential to understand the relationship between feet, miles, and time. One mile is equivalent to 5,280 feet, and to convert feet to miles, you need to divide the distance in feet by 5,280. When calculating speed in miles per hour, you also need to account for the time, which is commonly expressed in minutes. Since there are 60 minutes in an hour, the conversion to find the speed in miles per hour requires that you normalize the time to an hour. The correct formula indicates that you should first convert the distance from feet to miles by dividing the total distance by 5,280. Then, to find the speed in miles per hour, you can use the following relationship: MPH = (Distance in feet ÷ 5,280) ÷ (Time in hours) To simplify calculations when using a time in minutes, this can be rewritten as: MPH = Distance (ft) ÷ (5,280 ÷ 60) = Distance (ft) ÷ 88 By using 88 in the denominator, you effectively adjust your calculations to reflect the conversion from feet to miles as well
