Rate x Time = Distance
\n" ); document.write( "1. $\"R%2AT=D\"$
\n" ); document.write( "D = 20x+40 miles
\n" ); document.write( "R = 20 mph
\n" ); document.write( "From 1,
\n" ); document.write( "1. $\"R%2AT=D\"$
\n" ); document.write( " $\"cross%28R%29%2AT%2Fcross%28R%29=D%2FR\"$ Multiplicative inverse of R.
\n" ); document.write( " $\"T=D%2FR\"$
\n" ); document.write( " $\"T=%2820x%2B40%29%2F20\"$ Substitute.
\n" ); document.write( " $\"T=20x%2F20%2B40%2F20\"$ Distributive property.
\n" ); document.write( " $\"T=x%2B2\"$ Simplify. Units are hours since $\"miles%2F%28miles%2Fhr%29=hr\"$ \n" ); document.write( "

\n" );
