Answer:
A: 2 1/2 ft^2/h
B: 3 1/3 ft^2/h
B has the greater rate
Step-by-step explanation:
The rate in square feet per hour is found by dividing square feet by hours.
Machine A:
(5/8 ft^2) ÷ (1/4 h) = (5/8)×(4/1) ft^2/h = 5/2 ft^2/h = 2 1/2 ft²/h
Machine B:
(2/3 ft^2) ÷ (1/5 h) = (2/3)×(5/1) ft^2/h = 10/3 ft²/h = 3 1/3 ft²/h
Machine B has the greater rate.
