Terri and Judy run a lawn mowing business. If Terri can mow a large lawn in 8 hours and Judy can mow the same lawn in 12 hours, how long will it take them together to mow the lawn?
----------------
Terri does 1/8 lawn per hour
Judy does 1/2 lawn per hour
-------------
Together, they do 1/8 + 1/12 per hour = 5/24 lawn/hr
--> 24/5 hr/lawn
= 4.8 hour/lawn
