Alice paints at a rate of 10 square feet per minute and Bob paints at a rate of 8 square feet per minute. If they work together, how many square feet can they paint per minute?
ummm 10+8 ft^2/min
To find out how many square feet they can paint together per minute, you need to add up their individual rates.
Alice's rate of painting is 10 square feet per minute, and Bob's rate is 8 square feet per minute.
So, together they can paint at a rate of 10 + 8 = 18 square feet per minute.
Therefore, Alice and Bob can paint 18 square feet per minute when working together.
