The correct answer is:
11.
Explanation:
Since there are 5280 feet in 1 mile, and each home run is 500 feet, we would divide to find out how many we would need:
5280/500 = 10.56.
We cannot have 0.56 of a home run; we round this up to 11. Hitting 11 home runs at this distance would be 5500 feet, which is more than a mile.
