Question 387153: It takes jerry twice as long as sue to clean up the kitchen. if sure can clean up the kitchen in 1/3 hour, how long would it take to clean up the kitchen if she works together with jerry? Answer by lwsshak3(11628) (Show Source):
You can put this solution on YOUR website! sue can clean the kitchen alone in 1/3 hr or 20 minutes
jerry can clean the kitchen alone twice as long as sue =40 minutes
working together they can clean the kitchen in x minutes
sue's rate + jerry rate = the rate both working together
1/20 +1/40 =1/x
2/40 +1/40 =1/x
3/40 =1/x
x =40/3 =13.33 minutes
ans: working together sue and jerry can clean he kitchen in 13.33 minues
