At 1 hour from 1:10, the blue line bus has made it's 3rd stop
\n" ); document.write( "At Helen's stop, since \"+20+%2B+20+%2B+20+=+60+\"
\n" ); document.write( "At 1 hour from 1:10, the red line bus has made it's 2nd stop
\n" ); document.write( "At her stop, since \"+30+%2B+30+=+60+\"
\n" ); document.write( "So 1:10 + 1 = 2:10 is the next time that Helen can get off 1 bus
\n" ); document.write( "and get on the other one
\n" ); document.write( "
\n" );
