A is twice as fast as B and B is thrice as fast as C. The journey covered by C in 54 minutes will be covered by A in how many minutes?

Correct option is D

Given: ​

A is twice fast as B, 

and B is thrice as fast as C. 

c is covered Distance 54 minute

Formula Used:

Speed = $$\frac{Distance}{Time}$$​​

Solution: 

According to the question; 

Speed of A B and C 

A     B     C

6x    3x       x            

Now, 

C cover distance =  54$$\times$$x =  54x

A is cover distance in time = $$\frac{54x}{6x}$$ = 9 minute
