let s = Dave's speed
\n" ); document.write( "Katie bikes 6mph faster than Dave.
\n" ); document.write( "(s+6) = Katie's speed
\n" ); document.write( " Katie can bike 11 miles in the same amount of time that Dave can bike 8 miles.
\n" ); document.write( "write a time equation; time = dist/speed
\n" ); document.write( "\"8%2Fs\" = \"11%2F%28%28s%2B6%29%29\"
\n" ); document.write( "cross multiply
\n" ); document.write( "11s = 8(s+6)
\n" ); document.write( "11s = 8s + 48
\n" ); document.write( "11s - 8s = 48
\n" ); document.write( "s = 48/3
\n" ); document.write( "s = 16 mph is D's speed
\n" ); document.write( "then
\n" ); document.write( "16+6 = 22 mph is K's speed
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check, find the time of each
\n" ); document.write( "8/16 = .5 hrs
\n" ); document.write( "11/22 = .5 hrs\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
