It takes john 4 hours to mow a lawn. it takes mary 3 hours to mow the same lawn.
How long would it take if both of them worked together.

Obviously Mary is doing a half -assed job if it takes her only three hours and takes John four hours.
A man would never let his lawn look half-assed. So John will do it alone. Mary will then make iced-tea for John.
Trick question. Four hours.
EDIT_ I should read before I post… Bob Saget was right.
