在近年的中考试题中,经常出现以“两者距离”为变量的一次函数问题,比较棘手.下面举例说明这类问题的解法,供参考.例1(2015年·随州)甲骑摩托车从A地去B地,乙开汽车从B地去A地.两人同时出发,匀速行驶,各自到达终点后停止.设甲、乙两人间的距离为s km,甲行驶的时间为th.s与t之间的函数关系如图1所示.有 In recent years, the mid-term exam questions, often with “one of the two ” as a variable function of the problem, more difficult. The following examples illustrate the solution of such problems for reference. B car from A to B, B car to B from A to B. They start at the same time, uniform speed, each stop after reaching the end of the set A, B distance between the two is s km, A driving time th The functional relationship between .s and t is shown in Figure 1.
