对于某些数学问题,如果我们能多一分思考,就会多一分收获.不信的话,就来瞧瞧吧.问题:一辆自行车在一条平直的公路上行驶,公路各处的路况均相同.现有一种轮胎,若将其安装在这辆自行车的前轮处,则行驶5 000 km后报废;若将其安装在这辆自行车的后轮处,则行驶3 000 km后报废.如果自行车安装一对新的这种轮胎,行驶一定路程后,我们将前后轮胎交换位置,使这对轮胎能同时报废,那么这辆自行车最多能行 For some math problems, if we can think a little more, we will reap the benefits and if we do not believe, we will check it out. Problem: A bicycle runs on a straight road and the road conditions The same is true of a tire which, if installed on the front wheel of the bicycle, is discarded after traveling 5 000 km and is discarded after traveling 3000 km if it is installed at the rear wheel of the bicycle. Bicycles to install a new pair of these tires, traveling a certain distance, we will be the front and rear tire exchange position, so that the tires can be scrapped at the same time, then this bike can do at most
