You can put this solution on YOUR website!
I am starting this but may leave it unfinished. I am showing here a data table. Note that from slowest to fastest, P, Q, R. Naturally, R can depart last because he is the fastest and is expected to overcome distance traveled of P and Q. Assumes that a and b are positive real numbers. Let x be the travel time for R to catchup distance d to P and Q.\r

document.write( "TRAVELER      RATE        TIME       DISTANCE\r\n" );
document.write( "P             a           t+p+x         d\r\n" );
document.write( "Q             a+b         p+x           d\r\n" );
document.write( "R             a+2b        x             d\r\n" );
document.write( "

\n" ); document.write( "\n" ); document.write( "Travel Rate Rule using speed S is S*T=D.
\n" ); document.write( "The UNKNOWN variables in the example must be just t, x, and d. Question's interpretation mean you want to find the solution for x.\r
