Q.3 (Question:139763.0)

wrong answer

Question:
The speeds of scooter, car and train are in the ratio of 1 : 4: 16. If all of them covers equal distance then the ratio of time to speed of each of the vehicle is respectively:
Options:
A) 256 : 16 : 1
B) 1 : 4 : 16
C) 16 : 4 : 1
D) 16 : 1 : 4
Solution:

Since distance is constant. Therefore ratio of speeds of  scooter, car and train

= 1 : 4 : 16

and therefore, ratio of time taken = 16 : 4 : 1

Therefore, required ratio =  \(\frac{16}{1}\) : \(\frac{4}{4}\)  : \(\frac{1}{16}\)  

= 16 : 1 : \(\frac{1}{16}\)  = 256 : 16 : 1
