Joe walked to the edge of the jungle in 3 hours.
\n" ); document.write( " He ran back to camp in 1 hour.
\n" ); document.write( "How far away was the edge of the jungle if Joe ran 8 miles per hour faster than he walked?
\n" ); document.write( ":
\n" ); document.write( "Find the rate he walked first
\n" ); document.write( "r = walking speed
\n" ); document.write( "then
\n" ); document.write( "(r+8) = running speed
\n" ); document.write( ":
\n" ); document.write( "The dist there and back is equal so write distance equation: Dist = time * rate
\n" ); document.write( ":
\n" ); document.write( "3r = 1(r+8)
\n" ); document.write( ":
\n" ); document.write( "3r = r + 8
\n" ); document.write( ":
\n" ); document.write( "3r - r = 8
\n" ); document.write( ":
\n" ); document.write( "2r = 8
\n" ); document.write( ":
\n" ); document.write( "r = 4 mph he walked, 12 mph he ran
\n" ); document.write( ":
\n" ); document.write( "Find the distance to the jungle:
\n" ); document.write( "3 * 4 = 12 mi; walking
\n" ); document.write( "1 * 12 = 12 mi; running
\n" ); document.write( " \n" ); document.write( "
\n" );
