At the beginning of a walk Roberto and Juanita are 3.3 miles apart if they leave
\n" ); document.write( " at the same time and walk in the same direction, Roberto overtakes Juanita
\n" ); document.write( " in 11 hours if they walk towards each other they meet in 1 hour.
\n" ); document.write( " What are their speeds
\n" ); document.write( ":
\n" ); document.write( "Let r = R's speed
\n" ); document.write( "Let j = J's speed
\n" ); document.write( ":
\n" ); document.write( "Walking same directions equation
\n" ); document.write( "Write a dist equation: dist = time * speed
\n" ); document.write( "11r = 11j + 3.3
\n" ); document.write( "simplify divide by 11
\n" ); document.write( "r = j + .3
\n" ); document.write( ":
\n" ); document.write( "Walking toward each other equation, another dist equation
\n" ); document.write( "r + j = 3.3
\n" ); document.write( ":
\n" ); document.write( "Replace r with (j+.3)
\n" ); document.write( "(j+.3) + j = 3.3
\n" ); document.write( "j + j = 3.3 - .3
\n" ); document.write( "2j = 3
\n" ); document.write( "j = \"3%2F2\"
\n" ); document.write( "j = 1.5 mph is J's speed
\n" ); document.write( "then
\n" ); document.write( "r = 1.5 + .3
\n" ); document.write( "r = 1.8 mph is R's speed
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution in the 1st equation
\n" ); document.write( "11r = 11j + 3.3
\n" ); document.write( "11(1.8) = 11(.15) + 3.3
\n" ); document.write( "19.8 = 16.5 + 3.3 \n" ); document.write( "
\n" );
