Question 25

The speeds of 3 cars in the ratio 5:4:6. The ratio between the time taken by them to travel same distance is

Solution

Speed = Distance travelled$$\div$$time taken

So, for the same distance travelled, Speed is inversely proportional to time taken.

$$Speed\propto \frac{1}{time taken}$$

Given ratio of speeds of three cars  is 5 : 4 : 6.

So, ratio of the time taken to travel same distance is $$\frac{1}{5} : \frac{1}{4} : \frac{1}{6}$$

= 12 : 15 : 10
