D=RT OR D/R=T
\n" ); document.write( "D/40+D/45=4
\n" ); document.write( "(45D+40D)/(40*45)=4
\n" ); document.write( "85D/1,800=4
\n" ); document.write( "85D=4*1,800
\n" ); document.write( "85D=7,200
\n" ); document.write( "D=7,200/85
\n" ); document.write( "D=84.7 MILES IS THE DISTANCE FROM CHE TO DUE'S HOUSE.
\n" ); document.write( "2*84.7=169.4 MILES IS THE TOTAAL DISTANCE TRAVELED.
\n" ); document.write( "
