Answer to Question #161535 in Math for Emma

Question

The production rate for each of five machines is the same. Using these five machines, 600 parts are produced in 2.3 hours. How many hours will it take two of these machines to produce 600 parts?

Answer 1

If 600 parts are produced in 2.3 hours by 5 machines, then 2 machines will produce 2/5×600 = 240 parts in 2.3 hours or 600 parts in 2.3×5/2 = 5.75 hours.
