One, Train A, traveled north at a certain speed and the other, Train B, traveled south at twice the speed. After 4 hours, the trains were 600 miles apart. How fast was each train traveling? Use needs to input the initial speed of train a to being the simulation. Answer by checkley79(3056)   (Show Source): You can put this solution on YOUR website!D+RT 600=(x+2x)4 600=3x*4 600=12x 600/12=x x=50 mph ans. for the slower train. 2*50=100 mph ans. for the second train. PROOF: 600=(50+100)4 600=150*4 600=600
