A cat is playing in the backyard of his owner's place. It can be seen moving back and forth, such that in the first go, it goes 0.2 m to its left, turns back and goes on for 0.4 m. It turns back again and goes on for 0.8 m and then turns back again and goes on Q. for 1.6 m and so on. If the cat takes 2 seconds to cover the distance between the successive turns, then what is the ratio of the average speed to the magnitude of its average velocity during the first 10 seconds? (Assume that the backyard is sufficiently large) 0 1 O 2.82 O 1.41 O 1.73
