A certain distance is covered at a certain speed. If half of this distance is covered in 4 times of the time, then find the ratio of the two speeds.?

Correct Answer: 8 : 1

Explanation:

Let L km is covered in T h.
Then, first speed = L/T km/h
Again, L/2 km is covered in 4T h.
∴ New speed = (L/2 x 1/4T ) = (L/8T) km/ h
Ratio of speed = L/T : L/8T = 1 : 1/8 = 8 : 1
