PLEASE FORMAT THE QUESTIONS PROPERLY!

Also what do you mean by "What i will the s-t either s minus t or s to t"?

Original question is:

On the number line, if r<s, if p is halfway between r and s, and if t is halfway between p and r then (s-t)/(t-r)=
A. 1/4
B. 1/3
C. 4/3
D. 3
E. 4

Let r=0 and s=4 --> p is halfway between r and s: p=2;
t is halfway between p=2 and r=0: t=1;

(s-t)/(t-r)=(4-1)/(1-0)=3.

Answer: D.

P.S. On the GMAT we can often see such statement: \(k\) is halfway between \(m\) and \(n\) on the number line. Remember this statement can ALWAYS be expressed algebraically as: \(\frac{m+n}{2}=k\).

Hi dave13

Before I answer your question, what according to you is "halfway"? how do you define "halfway" and as per that definition what will be the "halfway" of 2 & 5

Hey dave13 ,

Halfway means middle of the two numbers.

So, If the distance between you and I is 1000 Kms, then the halfway between us will be 500 Kms away from both of us.

Does that make sense?
