Problem #3

The distance light travels in one year is approximately $5,870,000,000,000$ miles. The distance light travels in $100$ years is:

$\textbf{(A)}\ 587 * 10^8\text{ miles}\qquad \textbf{(B)}\ 587 * 10^{10}\text{ miles}\qquad \textbf{(C)}\ 587*10^{-10}\text{ miles} \\ \textbf{(D)}\ 587 * 10^{12} \text{ miles} \qquad \textbf{(E)}\ 587* 10^{ - 12} \text{ miles}$


Solution

The distance light travels in one year can also be written as $587 * 10^10$. In 100 years, light will travel $(587 * 10^10) * 100 = 587 * 10^12$

Therefore, our answer is $(D) 587 * 10^{12}$
