Question

If 1 mile = 5280 feet, use dimensional analysis to convert 7.2 mi to ft.

Answer 1

To convert 7.2 miles to feet using dimensional analysis, we can set up the conversion factor as follows:

1 mile = 5280 feet

Now, we can multiply both sides of the equation by 7.2 to convert the miles to feet.

(7.2 miles) x (5280 feet/mile) = (7.2 x 5280) feet

Calculating this, we have:

(7.2 x 5280) feet = 37,760 feet

Therefore, 7.2 miles is equal to 37,760 feet.
