Hi there.

I have a few questions which I could do with some guidance from the Gmat Prep Quant questions practice test. Unfortunately I don't think they give you any explanations so any guidance would be greatly appreciated.

Q1. (DS) Points A, B, C, D are on the number line, not necessarily in that order. If the distance between C & D is 8, what is the distance between B & D?
1) The distance between C & A is the same as C & B
2) A is to the left of D on the number line

Q2. A boat travelled upstream a distance of 90 miles at an average speed of (v-3) m.p.h. and then travelled the same distance downstream at an average speed of (v+3) m.p.h. If the trip upstream took half an hour longer than the trip downstream, how many hours did it take for the boat to travel downstream?

Q3. (DS) In the xy-plane, does the equation y = 3x + 2 contain the point (r,s)?
1) (3r + 2 - s)(4r + 9 - s) =0
2) (4r - 6 - s)(3r + 2 - s) = 0

Q4. If x > y^2 > z^4 which of the following could be true?
1) x > y > z
2) z > y > x
3) x > z > y

Q5. (DS - sorry don't know how to do the correct notation)
Is SQ ROOT((x-3)^2) = 3 - x?
1) x not equal to 0
2) -x * Abs (x) > 0

Thanks in advance for your help,
SD
