<PRE><B>Question 522714</B>
two cars are leaving a city, one traveling east and the other traveling west. 
the car going east is traveling at 66 mph and the car going west is traveling at 60 mph.
how long before they are 441 miles apart?
:
write an algebraic expression for the distance traveled by the car going east
66t
:
write an algebraic expression for the distance traveled by the car going west
60t
;
write an algebraic expression for the total distance traveled by the two cars
66t + 60t
:
write an equation to answer the question 
66t + 60t = 441
126t = 441
t = {{{441/126}}}
t = 3.5 hrs</PRE>
