I walk 4 mph!!
\n" ); document.write( "Gaining speed 19 -4= 15 mph
\n" ); document.write( "Headstart 4*3 =12 miles
\n" ); document.write( "Time to catch up 12/15=0.8 hours
\n" ); document.write( "Time to catch up =48 minutes
\n" ); document.write( "Algebraic solution
\n" ); document.write( "4(t+3)=19t
\n" ); document.write( "4t+12=19t
\n" ); document.write( "12=19t-4t
\n" ); document.write( "12=15t
\n" ); document.write( "t=0.8 hours
\n" ); document.write( "Distance to meeting 0.8*19=15.2 miles\r
