hey! i’m taking the gmat in two days, so i’ve been looking at your videos just to solidify what i know and approach problem solving differently. I see in the comments people got to the answer fairly quick, but for me it takes time to get there. Thanks for showing shortcuts & giving reason as to why use our headlights (what we already know) to get through the fog (what we don’t know)!

thanks so much!

I'm glad you found us and that you found this video helpful. Best of luck to you in a couple days! And if you end up having to retake the GMAT (God forbid!), I hope you'll consider one of our full courses. Let us know how it goes!

I just paused at 00:53 to write this (maybe rest of video is good): The analogy is flawed, on the GMAT you're not necessarily "driving on a road" but rather driving in an open field - going forward is by no means a guarantee to get to the intended destination.

I don't think this problem is hard at all.

no it is not hard dear....

I got A, is that correct?

@Dominate the GMAT Idk any

math formulas :) just used plain

ol' logic here. Hope this is 'hard'

but something tells me it's not ...+Qonita Badeges Yep! Nice job :)

I'm curious. Is this actually considered a hard problem?

+Joshua Walker It's not a 700-level question, no, but it's definitely above average difficulty. In my experience students have particular trouble with distance/rate word problems, so that makes it more challenging if you don't have a strong algebra background. More importantly, the tip explained in this video is versatile and super useful on other hard problems -- so even if you personally don't find this question tough, there will be harder problems you'll encounter for which this strategy may come in handy for you.

I love the metaphor "Drive through the Fog with headlights". I think it's a useful way to look at difficult, multistep problems.

Wouldn't it be great if every Gmat math is as "hard" as this one? It only test your knowledge of +, -, ×, ÷, and decimal point. This is a common math problem for 3rd graders is Asia. Singapore math workbooks have many like this. I take it as a joke if anyone say it is HARD Gmat problem.

What youre doing is extremely helpful however a little more attention to lighting and sound quality will definitely take your video to the next level. Thanks for the resource!

Convert r=dt by changing 8min/mile to 1mile/8min. Then you have 50*(1/8) and the rest is pretty simple.

Just to clarify, if d=rt, then r=d/t.

ì was quite excited that i could solve this but looking at the fact that everybody solved this so quickly this must be an easy question.

FAST solution - 50/8 is 6.25 (48/8=6 and 2/8=1/4=.25).

6.25-3.25 = 3. 3/2 = 1.5 (he has to run there AND back) - Answer is A. Less than 10 seconds.+R K Idk all these formulas though.

Just used common sense & logic

and got A. Glad it's right. ...Peace...@Caleb Miller me 8 :P

i solved it in 9 seconds

1mile/8min 1/8= 0.125mile a minute 0.125*50=6.25 miles, that's what he can still run. as he've already run 3.25, we sum it with 6.25 we'll have 6.25+3.25=9.50 we divide it by 2 because it' 2 paths with equal distances he should run, so we'll have 9.50/2= 4.75, this is the distance he should run for each path. As he've already run 3.25, we'll have 4.75-3.25=1.5 so 1.5 is the final answer,

thx so much

I'm not quite sure what you mean by "a useable value" isitwiseful. Are you meaning, how do we make sure the units match the units for distance and time? Please clarify and I'll try to answer. Also, you can learn all of the detailed content and strategies for all sorts of distance/rate/time problems in our "Common GMAT Word Problems" lesson on our website under the "Course & Lessons" tab --> "A la Carte GMAT Tutorials" --> "Common GMAT Word Problems."

Correct, the answer is A.
