Two trains leave stations 342 miles apart at the same time and travel toward each other. One train travels at 85 miles per hour while the other travels at 105 miles per hour. How long will it take for the two trains to meet?
----
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
