Question 443788: You must leave for campus in half an hour, or you will be late for class. Unfortunately, you are snowed in. You can shovel the driveway in 45 minutes and your brother claims he can do it in 36 minutes. If you shovel together, how long will it take to clear the driveway? Will this give you enough time before your parents return? Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! 1/45+1/36=?
8/360+10/360=18/360=1/20
If you shovel together, the driveway can be cleared in 20 minutes. Are you trying to get to class, or leave before your parents return home?
