If a runner has completed 5,280 feet, how many miles have they run?

When converting feet to miles, it’s important to know the relationship between the two units of measurement. Specifically, there are 5,280 feet in one mile.

In this scenario, the runner has completed 5,280 feet. To find out how many miles that is, you divide the total feet by the number of feet in a mile.

Thus, dividing 5,280 feet by 5,280 feet/mile gives the following calculation:

5,280 feet ÷ 5,280 feet/mile = 1 mile.

This confirms that the runner has effectively run one full mile. Therefore, the correct answer reflects the direct conversion from feet to miles, validating the understanding of unit conversions in measurement.
