Problem
Elmer the emu takes equal strides to walk between consecutive telephone poles on a rural road. Oscar the ostrich can cover the same distance in equal leaps. The telephone poles are evenly spaced, and the st pole along this road is exactly one mile ( feet) from the first pole. How much longer, in feet, is Oscar's leap than Elmer's stride?
(A)
(B)
(C)
(D)
Solution
There are gaps between the telephone poles, so the distance of each gap is feet. Each of Oscar's leaps covers feet, and each of Elmer's strides covers feet. Therefore, Oscar's leap is feet longer than Elmer's stride.
Final answer
B
