Rainforests in Indonesia are being cut at a rate of 300 "football fields" per hour. Assume that a football field is shaped like a rectangle. Each field measures 120 yards long and 53 yards wide. How many square miles of rainforest are being cut every hour? Round to the tenths place. One square mile is the same as 3.1 x 10^6 square yards.

0.6

Explanation:

Area of a football field (a rectangle) is 120 x 53 = 6360 square yards.

A rate of 300 "football fields" per hour is 300 x 6360 square yards = 1.9 x 10^6 square yards.

Now we can determine how many square miles of rainforest are being cut every hour:

1.9 x 10^6 : 3.1 x 10^6 = 0.615 square miles

Round to the tenths place: 0.6 square miles.
