Jimmy left 1 hr after Maria & traveled for 5 hrs,so
\n" ); document.write( "Maria traveled for 6 hrs
\n" ); document.write( "—————————————-
\n" ); document.write( "Let $\"+s+\"$ = Maria’s average speed
\n" ); document.write( "Let $\"+d+\"$ = distance from start where they meet
\n" ); document.write( "———————
\n" ); document.write( "Jimmy’s equation:
\n" ); document.write( " $\"+d+=+24%2A5+\"$
\n" ); document.write( " $\"+d+=+120+\"$ km
\n" ); document.write( "Maria’s equation:
\n" ); document.write( " $\"+d+=+s%2A6+\"$
\n" ); document.write( " $\"+120+=+6s+\"$
\n" ); document.write( " $\"+s+=+20+\"$ km/hr
\n" ); document.write( " \n" ); document.write( "
