a passenger train travels 100 mph faster than a car. in the time it take the car to travel 140 miles
the train can travel 340 mile. Find the speed of each.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

The equation is 

140%2Fc = 340%2F%28c%2B100%29,   (1)

where "c" is the speed of car (in mph), now unknown.

To solve (1), multiply both sides by c*(c+100).

And so on . . .
