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:
The distance between the astronomers and the moon was meters.
The equation of the line is given as 
A straight line equation is given in the form
where 
is the gradient and 
is the y-interest.
We need to rearrange to make 
the subject.
⇒ from here we can read the gradient and the y-intercept. The gradient, 
and
