A man drives a car 24 mph faster than he rides his bicycle.
\n" ); document.write( " It takes him the same amount of time to drive 144 miles as it takes him to ride his bike 48 miles.
\n" ); document.write( " what is the rate of speed for each?
\n" ); document.write( ":
\n" ); document.write( "The clue here is \"the same amt of time\", so write a time equation
\n" ); document.write( "time = dist/speed
\n" ); document.write( ":
\n" ); document.write( "let s = speed of the bike
\n" ); document.write( "then
\n" ); document.write( "(s+24) = speed of the car
\n" ); document.write( ":
\n" ); document.write( " $\"144%2F%28s%2B24%29\"$ = $\"48%2Fs\"$
\n" ); document.write( "Solve for x by cross multiplying \n" ); document.write( "

\n" );
