of an hour. How many square feet could the robot vacuum clean in 1 hour?
Simplify your answer and write it as a proper fraction, mixed number, or whole number.

Answer 1

If the robot vacuum can clean a 150-square-foot kitchen in 1/2 of an hour, then in 1 hour it can clean 2 times the area.

Thus, in 1 hour the robot vacuum can clean 2 x 150 = <<2*150=300>>300 square feet.

Therefore, the robot vacuum can clean 300 square feet in 1 hour.
