Distance between the two stations from where the two trains leave = 182 miles Speed of one train (S1) = 55 miles/hour Speed of the other train = 75 miles/hour Now Time taken by the two trains to meet = Distance/(S1 + S2) = 182/(55 + 75) = 182/130 = 1.4 hours From the above deduction, it can be concluded that the two trains will meet each other after 1.4 hours. I hope that the procedure is simple enough for you to understand.
Forgive me but they deleted my answer for it did not have any work to be shown providing you know how to do Algebra you get X= 12 as your outcome. <span />
