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


A) 4 : 1

B) 1 : 4

C) 2 : 1

D) 1 : 2

Correct Answer:
B) 1 : 4

Description for Correct answer:
case I \( \Large Speed = \frac{Distance}{Time} \)

case II \( \Large Speed = \frac{\frac{Distance}{2}}{2 \times Time} = \frac{Distance}{ 4 \times Time} \)

\( \Large = \frac{ \text{case I speed} }{\text{case II speed}} = \frac{\frac{Distance}{Time}}{\frac{Distance}{ 4 \times Time}} \)

So required ratio = 1 : 4
