Bub and Bette seem to be starting from the same place but at different times and speeds.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "________________rate__________time____________distance

\n" ); document.write( "Bubbette________42____________\"1%261%2F2\"____________d\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The actual distance is not known; but both times are known, and we know RT=D as a rule for uniform rates of travel. Equate the expressions for distance d.\r
