dist from station to trains = D
ta = time in hours from when A passes station to when trains A & B meet.
D = 80ta
D = 88(ta-15/60)
solve for ta
Time at catch-up = 1:20 AM + ta
ta = time in hours from when A passes station to when trains A & B meet.
D = 80ta
D = 88(ta-15/60)
solve for ta
Time at catch-up = 1:20 AM + ta
