Answer 1

Train A=80x+12*80
Train B= 100x
100x=80x+12*80
x=48

Answer 2

6:27+ 48 minutes

Answer 3

7:15

Answer 4

Since there is 12 minutes between the 2 trains passing the station, at the time train B passes the station, train A has traveled 16 miles (1/5 of 80).

Train B is making up 20 miles of the difference every hour. So in 16/20 = 4/5 of an hour, train B will catch up to train A. 4/5 of 60 minutes is 48 minutes.

So, 6:27 + 0:48 = 7:15pm
