Kris runs a 5 k (kilometer) race for charity. it takes her 1 hour. what is kris' average speed? asap 100 points

Speed = (distance) / (time to cover it)

1 hour = 3600 seconds

(5000 meters) / (3600 seconds) =

1.388... m/s .

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.
