Question 993070
You can walk 8 miles in the same time that it takes to travel 16 miles by car. If the car's rate is 2 miles per hour faster than you walking rate. The rate for walking is x and the rate for car in heavy traffic is x+2. Find the average rate of each. 
-------
Car DATA:
dist = 16 miles ; rate = x+2 mph ; time = d/r = 16/(x+2) hrs
------
You DATA:
dist = 8 miles ; rate + x mph ; time = 8/x hrs
-------
Equation:
time = time
16/(x+2) = 8/x
---
16x = 8x+16
8x = 16
x = 2 mph (your rate)
x+2 = 4 mph (car's rate)
