A. 12.5 m/s.

The average speed is defined as the relationship between the displacement made by a body and the total time it took to perform it.

The formula that will allow you to calculate the average speed is:

v = d/t, where d is the traveled distance and t the time it took to travel the distance.

We hace to convert 4 minutes to second:

(60 s/1 min)*(4 min) = 240 s

So, the average speed is:

v = 3000 m/240 s

v = 12.5 m/s

Answer:

Explanation:

The third-quarter moon, also known as the last quarter moon, rises around midnight and sets around noon. Crescent Waning From our vantage point, the Moon is nearly back to the point in its orbit where its dayside directly faces the Sun, and all we see is a thin curve

When you look at a waxing crescent moon, you see a thin fraction of the moon's illuminated side and a larger fraction of the moon's night side, which is submerged in the moon's own shadow. Earthshine on a waxing crescent moon

The Decline The Gibbous phase occurs when the illuminated portion of the Moon decreases from 99.9 percent to 50.1 percent. It begins shortly after the Full Moon and continues until the Third Quarter Moon. Waning refers to the fact that it is shrinking and becoming smaller, whereas gibbous refers to the oval-to-round shape.

Hope this helps you!
