Multiple choice

A certain distance is covered at a certain speed. If half of this distance is covered in double the time, the ratio of the two speeds is- कुछ दूरी किसी निश्चित गति से तय की गई है। यदि इससे आधी दूरी दुगुने समय में तय की जाये, तो दोनों गतियों का अनुपात है-

  1. 4 : 1

  2. 1 : 4

  3. 2 : 1

  4. 1 : 2

A Correct answer
Explanation

Let first speed be v1 covering distance d in time t. Second scenario: half distance (d/2) in double time (2t), so speed v2 = (d/2)/(2t) = d/(4t). Since v1 = d/t, we have v1/v2 = (d/t)/(d/4t) = 4:1. The ratio is 4:1, making option A correct.
