The ratio of speed of three racers is 3 : 2 : 4. What is the respective ratio of time taken by the three racers to cover the same distance?
Answer & explanation
Correct answer: option 4
When the distance is same,
Ratio of speed ∝ $\frac{1}{ratio\; of\; time}$
Ratio of speed = 3 : 2 : 4
Ratio of time = 4 : 6 : 3
