You can put this solution on YOUR website!
henry runs at a speed of 10mph and doug at a speed of 8mph
\n" ); document.write( " henry gives doug a half mile head start. how long will it take henry to catch doug?
\n" ); document.write( ":
\n" ); document.write( "You can do this in your head, their relative speed: 10 - 8 = 2mph
\n" ); document.write( ":
\n" ); document.write( "How long will it take to cover .5 mile at 2mph
\n" ); document.write( ":
\n" ); document.write( "Time = Dist/speed: $\".5%2F2\"$ = .25 hrs or 15 min
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "We d catches h, they will have traveled the same dist:
\n" ); document.write( "8(.25) + .5 = 2.5 mi
\n" ); document.write( "10(.25) + 2.5 mi \n" ); document.write( "

\n" );
