In the following figure there are two snakes of the same size slithering on the sand. Can you identify which of them would move faster and why?

उत्तर
A snake forms loops in its body while slithering. Each loop of the snake gives it a forward push by pressing against the ground. The snake with a large number of loops moves much faster than the snake with less number of loops. Thus snake “A” will move faster than snake “B”.
