To determine how many feet are in a mile, we can look at the provided data. Since 5 miles equal 26,400 feet, we can find the number of feet in 1 mile by dividing the total feet by the number of miles:
\[ \text{Feet in 1 mile} = \frac{26,400 \text{ feet}}{5 \text{ miles}} = 5,280 \text{ feet} \]
Thus, there are 5,280 feet in a mile.
