The ratio of speeds of A and B is 2:3 and therefore A takes 20 minutes less time than B. What is the ratio of time taken by A and B?
  • 12:3
  • 22:5
  • 33:2
  • 43:5
Answer:- 1
Explanation:-

Solution:
When distance is constant then Speed is inversely proportional to time.
ST = D
When distance constant,
S ∝ 1/T
So, ratio of time taken by A and B = 3:2.
