Algebra.Com's Answer #668079 by josgarithmetic(39617)![]() ![]() ![]() You can put this solution on YOUR website! A very typical catchup-travel type problem. Basic constant travel rate rule is RT=D. Time is best handled in quantities, and not as points on a time-line, but this is only to make handling easier values for analyzing and solving the problem.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Only a data table is presented here.
