The speeds of three cars are in the ratio of 2 : 3 : 5 Find the ratio of the time taken by the above cars to travel the same distance.
Correct Answer: Description for Correct answer:
We know that speed and time inversely proportional.
Ratio of time taken
\( \Large = \frac{1}{2} : \frac{1}{3} : \frac{1}{5} = \frac{30}{2} : \frac{30}{3} : \frac{30}{5} \)
[LCM of 2, 3, 5 = 30] = 15 : 10 : 6
