Algebra.Com's Answer #315591 by richard1234(7193) You can put this solution on YOUR website! I agree with the other tutor, bicycling is not \"additive\"; the fact that two people are bicycling does not mean that their respective speeds add up. Unless of course one becomes tired and they switch off occasionally. Poorly designed problem indeed. \n" ); document.write( " |
