## Thinking Mathematically (6th Edition)

Since 1 km = 100,000 cm, we need to move the decimal place 5 places to the right to convert from units of km to units of cm. $4690~km = 469,000,000~cm$ We can convert from units of cm to units of miles. $469,000,000~cm = \frac{469,000,000~cm}{1}\times\frac{1~in}{2.54~cm} \times \frac{1~ft}{12~in}\times\frac{1~mi}{5280~ft}$ $469,000,000~cm = 2914~mi$ $4690~km = 2914~mi$ The distance is 2914 miles.
