Answer:
The general rule is 
Step-by-step explanation:
Arithmetic sequence:
In an arithmetic sequence, the difference between consecutive terms is always the same, and this difference is called common difference.
The general rule of an arithmetic sequence is given by:

In which
is the first term and d is the common difference.
We can also find the nth term as a function of a term m, using:

a3 = -12 and a8 = -37
First we find the common difference. So






So

Finding the first term:

Since 



So the general rule is:


Answer:

Step-by-step explanation:
This is because you use Pythagorean theorem. a^2 + b^2 = c^2.
To answer this all you need to do is divide 120 by 50
120/50
2.4
So it will take 2 hours and 24 minutes (.4 of 60 to get the 24)
