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?Options15 : 3 : 53 : 5 : 1515 : 5 : 35 : 3 : 1
Solution
The correct answer is 5 : 3 : 1.
Here's why:
The speed and time are inversely proportional to each other. This means that if the speed of a car is high, it will take less time to travel the same distance and vice versa.
So, if the speeds of the cars are in the ratio 1 : 3 : 5, the time taken by them to travel the same distance will be in the inverse ratio of their speeds, which is 5 : 3 : 1.
