When Fritz drives to work his trip takes 35 minutes, but when he takes the train it takes 15 minutes. Find the distance Fritz travels to work if the train travels an average of 80 miles per hour faster than his driving. Assume that the train travels the same distance as the car.
If the plain takes 15 minutes, divide 60 by 15, because 60 minutes equals 1 hour, and the train travels at 80 miles per hour. And that equals 4, so then divide 80 by 4 and that's your answer...20
