alleryA one-metre-circumference globe models Earth at roughly what scale?
A1:400 million
B1:4 million
C1:40 million
D1:1 million
Answer & Solution
Correct answer: C. 1:40 million
1. Earth's circumference is close to 40 million metres.
2. A globe of one metre circumference shrinks it by that factor.
3. So the scale is 1:40 million; the other ratios do not match the numbers.
