Answer:
after 1 hr = 20 after 2 hrs =<em> </em> 40 after 3 hrs = 80 160 n 3 hrs
Yes, that's correct. All you do is add the two numbers together and then divide by 2!

This is because you can at most, factor out x² and y³
Answer:
The distance between the astronomers and the moon was
meters.
Step-by-step explanation:
We have that the speed is the distance divided by the time, so:

In this problem, we have that:
The reflected laser beam was observed by the astronomers 2.52 s after the laser pulse was sent. This means that
.
If the speed of light is 3.00 times 10^8 m/s, what was the distance between the astronomers and the moon?
We have that
m/s.
We have to find d. So:



![7.56*10^{8]](https://tex.z-dn.net/?f=7.56%2A10%5E%7B8%5D)
The distance between the astronomers and the moon was
meters.
