Question 982241: If jenna cleans her house in 4 hours and jodi,her daughter,cleans the house in 6 hours, how long will it talke for them to clean the house together? Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! Hi there
Jenna can clean her house in 4hours
Jodi can clean her house in 6hours
1/4 + 1/6 = 1/x
Common denominator = 24x
6x + 4x = 24
10x = 24
x = 2.4 hours
x = 2 hours 24 mins
This is how long they take together to clean
the house.
Hope this helps:-)
