This is an RTD question. Here is a table based on the given information
trains . . . . . . . .rate . . . . . . . . .time . . . . . . . .. distance
A . . . . . . . . . . . 35 . . . . . . . . . . t. . . . . . . . . . . .35t
B . . . . . . . . . . . 45. . . . . . . . . . t-2. . . . . . . . . . 45t - 90
total . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
8 am means t = 3.
we get
train A at a distance of 105
