Answer:
See attachment for plot
Step-by-step explanation:
Given

--- increment in the rate
First, we need to model the new rate
A linear equation is:

Where

Compare
and
. we have:

The above represents the previous rate.
The new rate:

Rewrite as:



So, the model is:


<u>The plot at 1 and 2 minutes</u>
When 

When 

So, we have:


<em>Whether she moves backwards or forward, the distance covered remains the same</em>

ANSWER

EXPLANATION
The given equation is

We add the additive inverse of 31 which is -31 to both sides of the equation to get,

Simplify;


When you say "Which number ...", I expect to see a list of choices at the
end of the question, and I get very upset when there's nothing there.
9h + 15 > 55
Subtract 15 from each side: 9h > 40
Divide each side by 9 : <em> h > 40/9</em>
Any number greater than (4 and 4/9) satisfies the inequality.
