A student must leave for campus in 10 minutes or he will be late for class. Unfortunately, he is snowed in. He can shovel the driveway in 20
minutes, and his brother claims to be able to do it in 14minutes. If they shovel together, how long will it take to clear the driveway? Will this give enough time for the student to get to the campus?
