Let's call the time from Center to New, T.
\n" ); document.write( "1. $\"220T=D\"$
\n" ); document.write( "The return trip took 1 hour less, or T-1.
\n" ); document.write( "2. $\"250%28T-1%29=D\"$
\n" ); document.write( "Since they're both equal to D, they're equal to each other.
\n" ); document.write( " $\"220T=250%28T-1%29\"$
\n" ); document.write( " $\"220T=250T-250%29\"$
\n" ); document.write( " $\"-30T=-250\"$
\n" ); document.write( " $\"T=8.33\"$
\n" ); document.write( "Using eq. 1,
\n" ); document.write( " $\"220%288.33%29=D\"$
\n" ); document.write( " $\"D=1833\"$
\n" ); document.write( "It is 1833 miles from New City to Center City.
\n" ); document.write( " \n" ); document.write( "
