John can mow his lawn in 3 hours and his sister, Julie, can mow it in 2 hours. How long will it take them to mow their lawn if they work together?
1 hour 12 minutes
If John does 1/3 of the job per hour and Julie does 1/2 of the job per hour, their combined work rate is 1/3 + 1/2 = 5/6 of the job per hour. Therefore, it will take them 6/5 hours, or 1 hour and 12 minutes, to complete the job together.
