\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If the two vehicles are traveling in opposite directions, then the distance each travels adds to the distance between them. Using the fact that distance equals rate times time, and at any given time, both will have traveled the same amount of time, we can say that the faster plane traveled\r

\n" ); document.write( "\n" ); document.write( " miles\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " miles\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "and the sum of these two distances is\r
