As part of an exercise regimen, you walk 2 miles on an indoor track. Then you jog twice your walking speed for another 2 miles. If the total time spent walking and jogging is 1 hour, find the walking and jogging rates.
\n" ); document.write( "-------
\n" ); document.write( "Walk DATA:
\n" ); document.write( "distance = 2 miles ; rate = x mph ; time = 2/x hrs
\n" ); document.write( "-----
\n" ); document.write( "Jog DATA:
\n" ); document.write( "distance = 2 miles ; rate = 2x mph ; time = 2/(2x) = 1/x hrs
\n" ); document.write( "------
\n" ); document.write( "Equation:
\n" ); document.write( "time + time = 1 hr
\n" ); document.write( "---
\n" ); document.write( "2/x + 1/x = 1
\n" ); document.write( "2 + 1 = x
\n" ); document.write( "x = 3 mph (Walking rate)
\n" ); document.write( "2x = 6 mph (Jogging rate)
