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.
\n" ); document.write( "-------
\n" ); document.write( "Car DATA:
\n" ); document.write( "dist = 16 miles ; rate = x+2 mph ; time = d/r = 16/(x+2) hrs
\n" ); document.write( "------
\n" ); document.write( "You DATA:
\n" ); document.write( "dist = 8 miles ; rate + x mph ; time = 8/x hrs
\n" ); document.write( "-------
\n" ); document.write( "Equation:
\n" ); document.write( "time = time
\n" ); document.write( "16/(x+2) = 8/x
\n" ); document.write( "---
\n" ); document.write( "16x = 8x+16
\n" ); document.write( "8x = 16
\n" ); document.write( "x = 2 mph (your rate)
\n" ); document.write( "x+2 = 4 mph (car's rate)
\n" ); document.write( "-----------
