The speed of a passenger train is 20 mph faster than the speed of a freight train. The passenger train travels 340 miles in the same time it takes the freight train to travel 240 miles. Find the speed of each train.
Answer provided by our tutors
Speed of frieght train = x mph
Speed of passenger train = x + 20 mph
340/(x + 20) = 240/x
240x + 4800 = 340x
100x = 4800
x = 4800/100 = 48 mph = Speed of frieght train
Speed of passenger train = 48 + 20 = 68 mph
