The ratio of speeds of A and B is 2 : 3 and therefore A takes 20 minutes more time than B. What is the ratio of time taken by A and B?

A. 2 : 3

B. 2 : 5

C. 3 : 2

D. 3 : 5

Answer: Option C

Solution(By Examveda Team)

When distance is constant then Speed is inversely proportional to time.
ST = D
When distance constant,
S ∝ $$\frac{1}{{\text{T}}}$$
So, ratio of time taken by A and B = 3 : 2
