@Xiggi, I see what you’re trying to say. My “easier” way is quite a misleading assertion. What I was trying to say is that it works well for me so I won’t get caught up in converting miles to hours, hours to miles, etc. Anyways, your way is definitely less time consuming and a better way if you already understand the concept behind the question . As for your 39 and 11 conversion, yes, it would not work well with my way but the SAT wouldn’t be that cruel to give you those data :)

@Muhammad The hour thing was just an addition to my response. The point is, your formula total distance / total time would get you the wrong answer.
