Rachel drove at a constant speed from inn A along a highway to inn B. Did Rachel reach inn B from inn A in less than an hour?


(1) If Rachel had driven to inn C that was 15 kilometers further down the highway, she would have taken 50% more time

(2) If Rachel’s average speed for the drive had been 20 kilometers per hour lesser, she would have taken 50% more time

  • a)
    Statement (1) ALONE is sufficient, but statement (2) alone is

    not sufficient to answer the question asked.

  • b)
    BOTH statements (1) and (2) TOGETHER are sufficient to

    answer the question asked, but NEITHER statement ALONE

    is sufficient to answer the question asked.

  • c)
    Statement (2) ALONE is sufficient, but statement (1) alone is

    not sufficient to answer the question asked.

  • d)
    EACH statement ALONE is sufficient to answer the question

    asked.

  • e)
    Statements (1) and (2) TOGETHER are NOT sufficient to

    answer the question asked, and additional data specific to the

    problem are needed.

Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Rachel drove at a constant speed from inn A along a highway to inn B. ...
Step 1 & 2: Understand Question and Draw Inference


Let distance between Inns A and B = D kilometers (km in short)

Let Rachel’s average speed = S kilometers per hour (kmph in short)

So, Time taken by Rachel to travel from A to B = D/S hours.


To Find: Is D/S < 1 ?


To answer the question, we need to know the value of ratio D/S


Step 3 : Analyze Statement 1 independent


Statement 1 says that: 'If Rachel had driven to inn C that was 15 kilometers further down the highway, she would have taken 50% more time’








So, not sufficient.


Step 4 : Analyze Statement 2 independent


Statement 2 says that: ‘If Rachel’s average speed for the drive had been 20 kilometers per hour lesser, she would have taken 50% more time’








Step 5: Analyze Both Statements Together (if needed)


From Statement 1: D = 30 km

From Statement 2: S = 60 kmph

Sufficient to find a unique value of the ratio D/S

Rachel drove at a constant speed from inn A along a highway to inn B. ...
Had driven 60 kilometers per hour, she would have reached inn B in 40 minutes.

Answer:

Statement (1) alone is not sufficient. We don't know how far inn C is from inn B and we don't know Rachel's speed.

Statement (2) alone is sufficient. If Rachel could have reached inn B in 40 minutes driving at 60 kilometers per hour, then she could not have taken more than an hour to reach inn B at any other constant speed. Therefore, Rachel did reach inn B from inn A in less than an hour.

The answer is (B), statement (2) alone is sufficient, but statement (1) alone is not sufficient.
