The sum of the speeds of two trains is 722.6 miles per hour. If the speed of the first train is 9.4 mph faster than that of the second train, find the speeds of each.
722.6/2= 361.3 9.4 /2 = 4.7 So speed of the first train is 361.3 + +4.7= 366 The speed of the second train is 361.3 - 4.7 =356.6 366 + 356.6 = 722.6mph Hope that helped
