In covering a certain distance, two persons travel at speeds in the ratio 18:12. What is the ratio of the time taken by them?

Correct option is A

Given:
Speed ratio of two persons = 18:12
Formula Used:
Time taken is inversely proportional to speed, i.e., Time ∝ 1/Speed
Solution:
Simplifying the speed ratio, we get 18:12 = 3:2. Since time is inversely proportional to speed, the ratio of time taken by them is the inverse of the speed ratio. Thus, the time ratio = 2:3.
