Distance = rate x time.


\n" ); document.write( "A travels 2.5 * 4.5 = 11.25 miles before B starts. The distance B has to cover to overtake A is 11.25 miles.


\n" ); document.write( "B overtakes A at the difference of their speeds: 7-4.5=2.5 MPH.


\n" ); document.write( "11.25 = 2.5*t so t = 11.25/2.5 = 4.5 hours. \n" ); document.write( "

\n" );
