Let say time = t
west bound Train travels 80/1hr. For t hours it is (80 x t).
East bound train travels 90/1hr. For t hours it is (90 x t).
Now they are traveling opposite to each other and if they travel exactly for 1 hour it will be 80 + 90. Now for t hours it will be
80t + 90t.
To be 442 miles apart the sum should be equal to 442.
Hence 80t + 90t = 442
170t = 442
t = 442/170
t = 2.6 hours. (0.6 x 60 = 36min)
It takes 2 hours and 36 min for the two trains to be 442 miles apart.
