A and B start from a given point and travel on a straight road at average speeds of 30 and 50 miles per hour respectively. If B starts 3 hours after A, find (a) the time and (b) the distance the travel before meeting.
\n" ); document.write( "

With T being time B traveled before meeting A, the DISTANCE equation is: 50T = 30(T + 3)
\n" );
document.write( "Solve that to get a time of  AFTER B left.
\n" );
document.write( "From this, you can easily find the distance traveled. \n" );
document.write( "

\n" );
