<PRE><B>Question 391833</B>
 the driving distance between Pensacola and Key west is 792 miles. 
Bus A leaves pensacola at 6:00 a.m. traveling at an average speed of 42 miles per hour. 
Bus B leaves Key west at 7:00 am traveling at an average speed of 33 miles per hour. 
At what distance, in miles, from Key west will the two busses meet? 
-----------------------------------
P to K DATA:
rate = 42 mph ; distance = x miles ; time = d/r = x/42 hrs.
-----
K to P DATA:
rate = 33 mph ; distance = 792-x miles ; time = (792-x)/33 hrs
----
Equation:
P-time - K-time = 1 hr
x/42 - (792-x)/33 = 1
------
Multiply thru by 42*33 to get:
33x - 42*792 + 42x = 33*42
----
75x = 825*42
x = 462 miles (meeting point from P to K
792-462 = 330 miles (meeting point from K to P
------
