How many acres are in a mile?
Correct Answer
B. 640 acres
Explanation
A mile is a linear measure, while an acre is a measure of area. To convert square miles to acres, we use the fact that 1 square mile equals 640 acres. This is derived from the fact that there are 5,280 feet in a mile, and an acre is 43,560 square feet. Therefore:
1 square mile = (5,280 feet x 5,280 feet) = 27,878,400 square feet.
