22 mph to work, 32 mph from work.
\n" ); document.write( "time to go to work is distance/speed. This is a form of the equation distance=speed*time.
\n" ); document.write( "The units are miles/(miles/hour)=hour.
\n" ); document.write( "tw=d/22
\n" ); document.write( "th=d/32
\n" ); document.write( "(d/22)+(d/32)=2.25 hours
\n" ); document.write( "multiply both sides by (32*22)
\n" ); document.write( "32d+22d=1584; (32*22*2.25)
\n" ); document.write( "54d=1584
\n" ); document.write( "d=29 1/3 miles.
\n" ); document.write( "time to work is 29(1/3)/22=1 hour 20 minutes (4/3 hours); 1.3333 hours;
\n" ); document.write( "(check with time from work 29(1/3)/32=0.916666 hours; 55 minutes.
\n" ); document.write( "They add to 2 hours 15 minutes. \n" ); document.write( "

\n" );
