Time taken by A, B, C to reach a same destination is in ratio 6:4:3. What will be the ration of speed at which they cover the distance?

Options
- 2:3:4
- 3:4:6
- 2:3:8
- None of These

CORRECT ANSWER : 2:3:4

Discussion Board
Solution

Since distance is same, therefore
time = 1 / (speed)
Now, ratio of time given is 6:4:3
Therefore, Ratio of speed will be (1/6) : (1/4) : (1/3)
Take LCM(6,4,3) i.e 12, Divide this LCM by denominator of every term,
i.e. (12/6) : (12/4) : (12/3)
Ratio of speed will be 2:3:4

Let the Distance be x

Speed = Distance / Time
= X/6 : X/4 : X/3
= 2X/12 : 3X/12 : 4X/12
= 2 : 3 : 4
THE RATIO OF SPEED
