Question

The speeds of three motor bikes are in the ratio 6 : 5 : 4. The ratio between the time taken by them to travel the same distance is :

Answer 1

By logic we know that as speed increases time decreases.So ratio of time taken by 3 motar bikes will be in opposite of their speed I.e.

Speed ratio=6:5:4

so time ratio=4:5:6.

Answer 2

The ratio between the time taken by them to travel the same distance is 20:24:30.

Step-by-step explanation:

Since we have given that

Speed of three motor bikes = 6:5:4

We need to find the ratio of time of three motor bikes.

As we know that ratio of time is reciprocal of ratio of speed.

So, it becomes,

$\dfrac{1}{6}:\dfrac{1}{5}:\dfrac{1}{4}\\\\=5\times 4:6\times 4:6\times 5\\\\=20:24:30$

So, the ratio between the time taken by them to travel the same distance is 20:24:30.
