At beginning of a walk Roberto and Juanita are 4.4 miles apart.
\n" ); document.write( " If they leave at the same time and walk in the same direction, Roberto overtakes Juanita in 11 hours.
\n" ); document.write( "If they walk towards each other they meet in 1 hour, what are their speeds?
\n" ); document.write( ":
\n" ); document.write( "Let r = R's walking speed
\n" ); document.write( "Let j = J's walking speed
\n" ); document.write( ":
\n" ); document.write( "Write two distance equation; dist = time * speed
\n" ); document.write( "Toward: 1r + 1j = 4.4
\n" ); document.write( "Same dir: 11r - 11j = 4.4
\n" ); document.write( ":
\n" ); document.write( "multiply the 1st equation by 11, add to the 2nd equation
\n" ); document.write( "11r + 11j = 48.4
\n" ); document.write( "11r - 11j = 4.4
\n" ); document.write( "--------------------addition eliminates j, find r
\n" ); document.write( "22r = 52.8
\n" ); document.write( "r = \"52.8%2F22\"
\n" ); document.write( "r = 2.4 mph is R's walking speed
\n" ); document.write( "Find J
\n" ); document.write( "2.4 + j = 4.4
\n" ); document.write( "j = 4.4 - 2.4
\n" ); document.write( "j = 2 mph is J's walking speed
\n" ); document.write( ":
\n" ); document.write( "Check solution in the 2nd equation
\n" ); document.write( "11(2.4) - 11(2) = 4.4
\n" ); document.write( "26.4 - 22 = 4.4 \n" ); document.write( "
\n" );
