Achild has maximum walking speed of 1.6 m/s. what is the length of the child's legs? 0.26 m

There's not enough information in the question to calculate the answer.

Knowing the child's walking speed, we would need to know how often s/he takes a step in order to calculate the length of their legs.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
