You can put this solution on YOUR website! The combined speed of both trains is 190 mph
They are 342 miles apart. They will meet in 342/190 hours or 1.8 hours or 1h48m

----
slower train DATA:
rate = 85 mph ; time = x hrs ; distance = r*t = 85x miles
----
faster train DATA:
rate = 105 mph ; time = x hrs; distance = 105x miles
---------------------
Equation:
dist + dist = 342 miles
85x + 105x = 342
190x = 342
x = 1.8 hrs = 1 hr 48 min
