Problem

The distance light travels in one year (one light-year) is

9.46\times10^{15}\,\text{m}

. The average distance between the Earth and the Sun (1 astronomical unit, AU) is

1.496\times10^{11}\,\text{m}

. Approximately how many times larger is a light-year than an AU? a)

6.3\times10^{3}

9.46\times10^{4}

6.3\times10^{4}

3.2\times10^{4}
