hero · Answer

I would subtract 1020 - 170 to get the true distance they actually traveled first.

@Hero  then wat would i do?

hero · Answer

Next you will add the distances together and set them equal to 850

hero · Answer

5x + 5(x + 10) = 850
5(x + x + 10) = 850
x + x + 10 = 850/5
2x + 10 = 170
2x = 170 - 10
2x = 160
  x = 160/2
  x = 80

x + 10 = 90

hero · Answer

Thus the speed of one train was 80 mph. The speed of the other was 90 mph
