You can put this solution on YOUR website!
Distance = rate x time


\n" ); document.write( "The first rider traveled 60*5 = 300 miles.


\n" ); document.write( "The second rider overtakes the first at 75-60 = 15 miles per day and must make up that 300 miles.


\n" ); document.write( "300 = 15 * t


\n" ); document.write( "300/15 = t = 20 days.
