------
Faster train DATA:
distance = x miles ; rate = 105 mph ; time = x/105 hrs
----
Slower train DATA:
distance = 494-x miles ; rate = 85 mph ; time = (494-x)/85 hrs
----------------------
Equation:
time = time
x/105 = (494-x)/85
85x = 105*494-105x
-----
190x = 105*494
x = 273 miles
---
Ans:: time = 273/105 = 2.6 hrs = 2hrs 36min
