Question 303500: Ron can make as many pizzas in 30 minutes as Jess can make in 40 minutes. How long will it take to make the same number if they both work? Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! I assume you mean they work together at the same job at the same time.
x/30+x/40=1
4x+3x=120
7x=120
x=120/7
