Question 652579


Jack cleans the house at the rate of {{{1/4}}} house per hour

Jose cleans house at the rate of {{{1/6}}} house per hour

Adding {{{1/4 + 1/6=(3+2)/12}}} gives you {{{5/12}}}. 

So together they clean {{{5/12}}} of a house in one hour.

To clean one house together, it will take them {{{5/12=1/x}}} of an hour, or  
{{{5x=12}}}

{{{x=12/5}}} which is {{{x=2.4}}} hours or {{{x=2}}} hours and {{{.4*60=24}}} minutes
