Question

If a new segment of the fence has 13 new posts, using the last post from the previous section of fence as a starting point, how long is the new segment of fence?

A. 17 1/2 ft

B. 52 1/2 ft

C. 58 1/2 ft

D. 52 ft

Answer 1

Hi Hannah, this is one of those trick questions where they try to make you include the last fence post of the new section used in the calculations, which would make the fence 4.5 feet longer that it is.

The calculation starting at the last post from the previous section is just 13 times 4.5, or answer C, 58.5 feet. The last fence post from the new section, is just that, the last fence post entered and does not change the calculation.
