I answered partially you can see . Just the years couldn't do 

**Question 10 of 10**

\[
\frac{w(10) - w(0)}{10 - 0} = 14
\]

\[
\frac{w(20) - w(10)}{20 - 10} = 5.5
\]

(b) Compare your answers in (a). What does this tell you about atmospheric methane levels? Enter a year in each box to complete the explanation.

This tells us that the methane level rises at a slower average rate from the years [ ] to [ ] than from the years [ ] to [ ].

## Understanding Atmospheric Methane Levels

Methane is a greenhouse gas implicated as a contributor to global warming. The table below shows the atmospheric methane level in parts per billion (ppb) for various years after 1980.

| \( t \)  | 0    | 5    | 10   | 15   | 20   | 25   | 30   |
|----------|------|------|------|------|------|------|------|
| \( Q \)  | 1575 | 1660 | 1715 | 1750 | 1770 | 1775 | 1785 |

### Calculations and Interpretation

**(a) Evaluate** 
\[
\frac{w(10) - w(0)}{10 - 0} \quad \text{and} \quad \frac{w(20) - w(10)}{20 - 10}
\]

Round your answers to one decimal place.

\[
\frac{w(10) - w(0)}{10 - 0} = 14
\]

\[
\frac{w(20) - w(10)}{20 - 10} = 5.5
\]

**(b) Compare your answers in (a).**

What does this tell you about atmospheric methane levels? Enter a year in each box to complete the explanation.

This tells us that the methane level rises at a slower average rate from the years \(\boxed{10}\) to \(\boxed{20}\).
