If a lake sits 3 miles from a property line, how many feet is the lake from the property?

To convert the distance from miles to feet, you should know that there are 5,280 feet in one mile. Therefore, to find out how many feet there are in 3 miles, you multiply the number of miles by the number of feet per mile:

3 miles * 5,280 feet/mile = 15,840 feet.

This calculation shows that a lake situated 3 miles away from a property line is indeed 15,840 feet from that line. This is why the correct answer is the one that matches this conversion. The other options do not align with the correct multiplication and thus do not represent the correct conversion from miles to feet.
