A meteor moving 468 km/min traveling in a south-to-north direction passes near Earth in 2013. Because the meteor was only 45 m wide and was 27,700 km above Earth’s surface, it was not visible without the aid of a telescope. Calculate the average speed of the meteor in km/sec as it heads northward.

7.8km/sec

Step-by-step explanation: Being that we need to convert it from minutes to seconds causes it to be a decrease. Knowing this we divide the 468km by 60 due to the amount of seconds in a minute, this gives us our answer of 7.8km/sec.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
