Question
Select the correct answerThe speeds of three cars are in the ratio of 1 : 3 : 5. The ratio among the time taken by these cars to travel the same distance is?Options3 : 5 : 1515 : 5 : 35 : 3 : 115 : 3 : 5
Solution
The correct answer is 5 : 3 : 1.
This is because the time taken to travel a certain distance is inversely proportional to the speed. If one car is faster, it will take less time to travel the same distance. So, if the speed ratio is 1:3:5, the time ratio will be the reciprocal, which is 5:3:1.
