one meter two meters three meters four meters
I gave my students this multiple choice question: Daphnee is going to build a model of the solar system for her science project. She decides that a meter (m) will represent one astronomical unit (AU) in her model. Based on this scale, how far away from the Sun would she need to place Earth?

Only one answer is correct among these 4 choices:
- one meter
- two meters
- three meters
- four meters

Could you tell me which one is correct?

one meter
