qThrough investigations of real-life contexts, students develope a rich understanding of important mathematics that makes sense to them and which, in turn, enables them to make sense out of new situations and problems.q--P. 1.The Horse model of the Troy-Bilt Roto Tiller has two forward speeds when the engine drive shaft has angular velocity of 3, 000 rpm. ... The tiller assembly turns at 146 revolutions per minute at both speeds. ... To avoid large driver pulleys, two or more pulley-belt systems may be hooked together so that the follower in oneanbsp;...
