Find the distance Fritz travels to work if the train travels an average of 48 miles per hour faster than his driving. : Change 20 min to hrs Change 36 min to hrs : Find his speed first Let s = car speed then (s+48) = train speed : Write a distance equation; dist = time * speed (s+48) = s multiply both sides by 15 to get rid of the denominators; results 5(s+48) = 3(3s) 5s + 240 = 9s 240 = 9s - 5s 240 = 4s s = 240/4 s = 60 mph in the car Find the distance * 60 = 36 mi : Check the distance using the train (60+48) = 108 mi mph * 108 = 36 mi also, confirms our solution of 36 mi
