CAT 1993 — QA Question 44

Relative SpeedEasy

Passage / Data

Directions for next 3 questions:

Q started to move from point B towards point A exactly an hour after P started from A in the opposite direction. Q’s speed was twice that of P. When P had covered one-sixth of the distance between the points A and B, Q had also covered the same distance.

How many more hours would P (compared to Q) take to complete his journey?

Answer & solution

Correct answer: 6

A
4
B
5
6
D
7

Solution

As P takes 12 hours to complete his journey, so Q moving with twice the speed of P will take $\frac{12}{2} = 6$ hours to complete his journey.

Hence P will take 6 hours more than Q to complete the journey.

Hence, option (c).
