I like to think of one train as standing still
and the other one approaching at the sum of their speeds
from 11 AM to 1 PM is 2 hrs
Let = the speed of the slower train
= the speed of the faster train
-----------------
The trains were traveling at 65 mi/hr and 101 mi/hr
check:
OK

D=RT
332=R*3
R=332/3
R=110.67 TOTAL SPEED OF THE 2 CARS.
X+X+36=110.67
2X=110.67-36
2X=74.67
X=74.67/2
X=37.335 MPH FOR THE SLOWER CAR.
37.335+36=73.335 MPH FOR THE FASTER CAR.
PROOF:
332=(37.335+73.335)*3
332=110.67*3
332=332
