What formula is used to determine Length?

To determine the length of a journey based on running time and speed (in miles per hour), the formula involves multiplying the running time by the speed and then scaling it appropriately. The correct answer involves taking the running time and multiplying it by the miles per hour to calculate the total distance traveled. Since running time is typically measured in minutes, the division by 60 is necessary to convert the calculation into hours, aligning with the units of miles per hour.

This method derives from the basic relationship in physics between distance, speed, and time, expressed in the equation: Distance = Speed × Time. Here, the running time needs to be expressed in hours (hence the division by 60). This way, the formula accurately calculates the distance traveled over the given time at a constant speed.
