Algebra.Com's Answer #738194 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! D=40+85(3)+60(2), since the pace is constant (presumably constant for each part, not the whole thing).\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The domain is [0, 6] This is the duration of the 6 hour trip. \n" ); document.write( "The range is [0. 415] This is the possible miles traveled during any time in the domain. \n" ); document.write( "The assumptions are constant speed for the entire hour for the first, three hours for the middle, and 2 hours for the end.
