<PRE><B>Question 497112</B>
Please help me solve this problem below. If only I knew how to set it up then I would understand. 
If you go on a road trip of 210 miles in the mountains and one half of the trip is downhill, how many miles of the trip are not downhill? 
---
Equation:
uphill + downhill = 210
uphill + (1/2)210 = 210
---
uphill + 105 = 210
uphill = 210-105
uphill = 105 miles
