Multiple choice

The ratio of the time taken by three cars to cover a certain distance is 6 : 2 : 3. Find the ratio of the speeds of these cars to cover the same distance. किसी निश्चित दूरी को तय करने में तीन कारों की चालों का अनुपात 6 : 2 : 3 है । समान दूरी को तय करने में इन तीन कारों द्वारा लिए गए समय का क्रमशः अनुपात ज्ञात कीजिये|

  1. 3 : 2 : 1

  2. 1 : 2 : 3

  3. 1 : 3 : 2

  4. 2 : 1 : 3

C Correct answer
Explanation

The question states the ratio of time taken is 6:2:3. Since speed = distance/time and distance is constant, speed is inversely proportional to time. Therefore, the ratio of speeds is the reciprocal of the time ratio: 1/6 : 1/2 : 1/3 = 1 : 3 : 2 when normalized.
