The equation a = 640s gives the relationship between s square miles and a acres. James owns 2.5 square miles of farmland. How many acres does he own?

Question

160 acres

1,600 acres

0.39 acres

3.91 acres

Answer 1

Option 2: 1,600 acres

To find how many acres James owns, we can substitute s = 2.5 into the equation a = 640s:

a = 640(2.5)
a = 1,600

Therefore, James owns 1,600 acres of farmland.
