Rate * Time = Distance
\n" ); document.write( " $\"R%5Bc%5D%2At=100\"$
\n" ); document.write( " $\"R%5Bb%5D%2At=40\"$
\n" ); document.write( " $\"R%5Bb%5D=R%5Bc%5D-30\"$
\n" ); document.write( "Substituting,
\n" ); document.write( " $\"40%2Ft=100%2Ft-30\"$
\n" ); document.write( " $\"-60%2Ft=-30\"$
\n" ); document.write( " $\"t=2\"$ $\"hr\"$
\n" ); document.write( "So then,
\n" ); document.write( " $\"R%5Bc%5D=100%2F2\"$
\n" ); document.write( " $\"R%5Bc%5D=50\"$ $\"mph\"$
\n" ); document.write( " $\"R%5Bb%5D=50-30\"$
\n" ); document.write( " $\"R%5Bb%5D=20\"$ $\"mph\"$ \n" ); document.write( "

\n" );
