问题 In New York, Manhattan Streets and Avenues are arranged in grid fashion. In the new town of "Grid", they copied the New York system. Eleven friends who all lived in street-corner dwellings, arranged to meet for lunch. On which street-corner should they meet, to give the least amount of total walking distance?
选项 A、Avenue 4, Street 2.
B、Avenue 4, Street 3.
C、Avenue 4, Street 4.
D、Avenue 4, Street 5.
答案 B
解析 在每一条Street上的将街号累加1×2+2×3+3×1+4×3+5×1+6×1=34，平均数约等于3。在每一条Avenue上的将街道号累加2×3+3×2+4×1+5×3+6×1+7×1=44，平均数等于4。所以选B。
