The sum of the speeds of two trains is 718.8 miles per hour. If the speed of the first train is 3.2 mph faster than that of the second train, find the speeds of each train.
------
slower train speed:: x mph
faster train speed:: x + 3.2 mph
------
Equation::
2x + 3.2 = 718.8 mph
-------
2x = 715.6 mph
x = 357.8 mph slower train speed
x+3.2 = 361 mph faster train speed
