<PRE><B>Question 921606</B>
Lamar drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 8  hours. 
When Lamar drove home, there was no traffic and the trip only took 5 hours. 
If his average rate was 21 miles per hour faster on the trip home, how far away does Lamar live from the mountains?
----------------------
From Home::
time = 8 hrs ; rate = x  mph ; distance = 8x miles
-------
To Home::
time = 5 hrs ; rate = x+21 mph ; distance = 5(x+21) = 5x + 105 miles
--------
Equation:
8x = 5x + 105
3x = 105
x = 35 mph 
-----
Ans: distance to mountains = 8x = 8*35 = 280 miles
