Question

A student uses four different tape-measures to estimate the length of a ruler manufactured to be exactly 1 foot long. Which measurement is most accurate?
A. 12.005 in
B. 12 in
C. 10 in
D. 11.5 in

Answer 1

B) 12 inches would be the most accurate measurement. 

Since the ruler is exactly 1 foot long, the most accurate measurement is 12 inches. 12.005 is a tempting answer, since it is the most specific/exact, but 12 inches is the most accurate, since this is equal to exactly one foot.

Answer 2

B. 12 in i’m pretty sure this is the answer :)
