You can think of one of the motorists as standing still
\n" ); document.write( "and the other one traveling at the sum of their speeds
\n" ); document.write( "So $\"+400+\"$ miles will be covered by a car going
\n" ); document.write( " $\"+42+%2B+38+=+80+\"$ mi/hr
\n" ); document.write( " $\"+400+=+80t+\"$
\n" ); document.write( " $\"+t+=+5+\"$ hrs
\n" ); document.write( "They will meet 5 hrs after 1 PM or 6 PM
\n" ); document.write( " \n" ); document.write( "
