<p>This question looks very wordy, so it's best that we approach it <strong><span style="color:#8e44ad;">Piece by Piece</span></strong>.</p>
<blockquote>
<p>The Sun is approximately 1,400 million kilometers from the planet Saturn,</p>
</blockquote>
<p>So, we know that the distance/work is $1400\,million\,kilometers$.</p>
<blockquote>
<p>and light from the Sun travels to Saturn at the rate of approximately 300,000 kilometers per second.</p>
</blockquote>
<p>So, we know the speed/rate is $300\,thousand\,kilometers\,per\,second$. Let's convert this to millions of kilometers to be consistent with our distance, so this would be $0.3\,million\,kilometers\,per\,second$.</p>
<blockquote>
<p>Approximately how many minutes</p>
</blockquote>
<p>Okay, so now it would be a good idea to convert our speed/rate into minutes:</p>
<p>Since each minute has $60$ seconds, $0.3\,million\,kilometers\,per\,second$. would be $(0.3*60)\,million\,kilometers\,per\,minute$., which is $18\,million\,kilometers\,per\,minute$.</p>
<blockquote>
<p>does it take for light to travel from the Sun to Saturn?</p>
</blockquote>
<p>Now, we just need to solve for time:</p>
<ul>
<li>$time = \frac{work}{rate}$</li>
<li>$time = \frac{1400\,million\,kilometers}{18\,million\,kilometers\,per\,minute}$</li>
<li>$time = 77.78\,minutes \sim 80\,minutes$</li>
</ul>
<p>So, the correct answer choice is <span style="color:#27ae60;">A</span>.</p>
