The easiest way to solve this problem is to break it down in pieces meters per second = m/s How many meters per second? So we use X as the unknown variable, so you end up with mx/s. Now the last part of the question requires an answer in minutes, so we convert the unit seconds into minutes, which gi...

50th percentile info: 50th % V: 28 50th % Q: ~37 50th % Overall: ~550 So an above average score would be over 550. However, it depends where you want to apply/your pool -- around here and at top b-schools an "above average" score is considered 680+. Thanks! I was looking at USC's M.S in H...

If interst for 2 years is 600 then interest for 3 years is 900 for d dollars.

Now subtract each overlapping option air+radio 6, air+pw 2, pw+radio 4, all options 3 = 38-15=23. Now the total # of cars is 25-23=2 2 is the answer. The 3 is from the overlap of all option, w...

Ignore this question. The answer is incorrect. The answer that you came up with is correct. This is the only question in the OG 11 that's flawed. Source: GMAT instructor, Brent from www.leapeducation.ca. This problem has been reported to GMAC and they are aware of it.

The rule is less modifies a singular noun. Fewer modifies a plural noun. Whenever you see a question that ask you to determine which word to use, identify the noun. In your first sentence species was the noun that fewer was modifying. In your second sentence the noun was "the number" ther...

D--is the right answer. All you need is one math operation to solve the problem. What you have to do is plug in the operations and see if it holds. Start with the simplest one, and that is addition. Work it out and you'll see that Each Statement Alone is Sufficient. mbadrew, [D] is not the right an...

You'll never find a confusing and senseless problem like this in the OG; even in the 700 range of difficulty.

D--actually strengthens the arguement, because it shows that relocation of retirees has increased in other states and it doesn't mention anything about Florida.
