Quantitative Aptitude(IBPS PO) Time & distance

Vikram travel a certain distance from point X to Y with a speed S kmph. If he travels the same distance with a speed (S+12) kmph, he reaches his destination 1 hour before. But if he travels with a speed of (S – 4) kmph, he reaches 30 min late. Which of the

following values we can find from the given conditions.

A) Speed of Ram, with which can travel the same distance in 3 hours

B) Speed of Vikram, when he reaches 30 minutes late

C) Distance between X and Z, if Z lies in between X and Y

Explanation:

Let the distance between X and Y be d
Time taken to travel the distance = t
Given, speed = S
So, s=d/t
If he travels the same distance with a
speed (S+12) kmph, he reaches his
destination 1 hours before.

So, we can calculate the value of S, d, t
A. Speed of Ram, who can travel the same distance in 3 hours: if distance can be calculated and as the time is given then the speed can be calculated.
B. Speed of Vikram, when he reaches 30 minutes late: as we can find the value of t and d, speed can easily be calculated.
C. Distance between X and Z, if Z lies in between X and Y: cannot be calculated as the ratio or any other information is not given.
D. Value of S: it can be calculated
So option (a) is the correct answer.
