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.
