A meteor moving 468 km per minute traveling in a south-to-north direction passed near Earth in 2013. Does this statement describe the meteor’s speed or velocity? Why did you choose the answer above (explain why)?

Yes, this does describe the speed and velocity.

Step-by-step explanation:

The dictionary definition of speed is "the rate at which someone or something is able to move or operate", which is stated. The speed is 468 km per minute. The dictionary definition for velocity is "the speed of something in a given direction". We know the speed, and the direction is also given (south to north direction) therefore, the velocity and speed are both described.

this is answer of 144 cubic meters

if x = 1, then the answer is 3.5
