Andy starts walking from point a at 2 miles per hour.
\n" ); document.write( "One-half hour later, Aaron starts walking from point a at 3.5 miles per hour and follows the same route.
\n" ); document.write( " How long will it take Aaron to catch up with Andy?
\n" ); document.write( ":
\n" ); document.write( "let t = Aaron's travel time to catch up with Andy
\n" ); document.write( "then
\n" ); document.write( "(t+.5) = Andy's travel time when he is caught
\n" ); document.write( ":
\n" ); document.write( "They both walked the same distance, write a distance expression for each.
\n" ); document.write( "dist = speed * time
\n" ); document.write( "3.5t = 2(t+.5)
\n" ); document.write( "3.5t = 2t + 1
\n" ); document.write( "3.5t - 2t = 1
\n" ); document.write( "1.5t = 1
\n" ); document.write( "t = 1/1.5
\n" ); document.write( "t = $\"2%2F3\"$ hr or 40 min for Aaron to catch him
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "You can confirm this yourself, find the distance each traveled should be the same. \n" ); document.write( "

\n" );
