Question

已知 $1$ 英里 $= 8$ 弗隆，且 $1$ 弗隆 $= 40$ 杆，那么一英里有多少杆？

Given that $1$ mile $= 8$ furlongs and $1$ furlong $= 40$ rods, the number of rods in one mile is

$5$

$320$

$660$

$1760$

$5280$

一英里是 $8$ 弗隆，每弗隆是 $40$ 杆，所以一英里是 $8 \times 40 = 320$ 杆。

所以正确答案是 B。

One mile is $8$ furlongs, and each furlong is $40$ rods, so one mile is $8 \times 40 = 320$ rods.

Thus, the correct answer is B .
