The sped of a passenger train is 14mph faster than the speed of a freight train. The passenger train travels 280 miles in the same time it takes the freight train to travel 210 miles. Find the speed of each train.

Question

In these written questions the hard part is to find the equations. 
Let x be the speed of the slower train, than the faster trains speed is x+14.
Now the distance travelled is speed*time. So we have two equations (t is time)
x*t=210
(x+14)t=280
dividing the two equations give
(x+14)/x=280/210
Hope you can solve this.
