<PRE><B>Question 356544</B>
A plane averaging 120 mi/h and an express train averaging 60 mi/h depart at the same time from the same city headed for the same destination.If the train arrives 45 min later than the plane, how far did they each travel?
----------------
Plane DATA:
rate = 120 mph ; time = x hrs ; distance = 120x miles
---------------------------
Train DATA:
rate = 60 mph ; time = x+(3/4) hrs ; distance = 60(x+(3/4) = 60x+45 miles
-----------------------
Equation:
distance = distance
120x = 60x+45
60x = 45
x = 3/4 hr 
-----
Distance = 120x = 120(3/4) = 90 miles
