<PRE><B>Question 766267</B>
A car leaves a station, traveling west at 55 mph. A truck leaves the same station one hour later, traveling west on the same road at 65 mph. How long does it take for the truck to pass the car?
-----------
Car DATA:
rate = 55 mph ; time = x hrs ; distance = 55x miles
-------
Truck DATA:
rate = 65 mph ; time = x-1 hrs ; distance = 65(x-10 miles
-------------
Equation: 
distance = distance 
55x = 65x - 650
-10x = -650
x = 65 hrs</PRE>
