If you assume the busses ran at regular intervals, the deciding factor is the speed of the walker (2 mph), which allows him to meet 10 more busses than pass him. The solution can be found by algebra or common sense. The common sense might take up 12 pages, so here is the algebra: 50 (X-2) = 40 (X+2) which results in 18 as the value of "x" and thus the average speed of the bus.Doesn't match Missing info Like question
