\n" ); document.write( "-------
\n" ); document.write( "Walk DATA:
\n" ); document.write( "rate = 5 mph ; distance = x miles ; time = d/r = x/5 hrs.
\n" ); document.write( "------------------------------
\n" ); document.write( "Jogging DATA:
\n" ); document.write( "rate = 8 mph ; distance = 2x miles ; time = d/r = 2x/8 hrs
\n" ); document.write( "-----
\n" ); document.write( "Equation:
\n" ); document.write( "time + time = 2 1/4 = 9/4 hrs.
\n" ); document.write( "x/5 + 2x/8 = 9/4 hrs
\n" ); document.write( "---
\n" ); document.write( "Multiply thru by 40 to get:
\n" ); document.write( "8x + 10x = 90
\n" ); document.write( "18x = 90
\n" ); document.write( "x = 5 miles
\n" ); document.write( "-----
\n" ); document.write( "Total Distance = walk + jog = x+2x = 3x = 15 miles
