SAT Q o D

<p>The</a> Official SAT Question of the Day</p>

<p>I only got up to 20/3 and I realized that either A or B was the answer. I don't know how to approach the step after I got 3x = 20.</p>

<p>This is the way I did it. I think it’s pretty simple. </p>

<p>If the mechanic does 3 cars every four hours, then that means it is 3 cars for 240 minutes, or 1 car per 80 minutes.</p>

<p>So, if the mechanic has do to 5 cars, that is 400 minutes. 400 minutes= 6 hours 40 minutes.</p>

<p>He does 20/3 hours</p>

<p>Or 6 hours and 2/3 hours
Or 6 hours and 40 minutes</p>
