Using what's only in chapter one

Question

The Nature of Science
Models, Theories, and Laws
Measurement and Uncertainty; Significant Figuers
Units, Standards, and SI System
Converting Units
Order of Magnitude: Rapid Estimating
Dimensions and Dimensional Analysis

How am I suppose to answer this?

Suggest a way to measure the distance from Earth to the Sun?

I took normal high school physics and can answer this question not using stuff from this chapter but I'm only suppose to use stuff from chapter one and don't know how to answer this question...

This book seems to becoming over simplified but hey it's only chapter one... they are probably looking for some very simple answer which I don't have one

Thank You!
