Help - simple algebra

How do you solve this problem

If Sally can paint a house in 4 hours, and John can paint the same house 
in 6 hour, how long will it take for both of them to paint the house 
together?

	2 hours and 24 minutes
	3 hours and 12 minutes
	3 hours and 44 minutes
	4 hours and 10 minutes
	4 hours and 33 minutes

Apparently it's 2 hours and 24 minutes

Thanks

Martin
