Question

Earth follows an elliptical orbit around theSun. At its nearest point on the orbit, it isabout 147 million kilometers from the Sun.At its farthest point, it is about 152 millionkilometers away. What is the percent change, rounded to the nearest tenth, from its nearest point to its farthest?

Answer 1

3.4%

Explanation:

We can calculate the percentage of change knowing the two values to be taken into account, just like this:

`\begin{gathered} p=(b-a)/(a)\cdot100 \\ \text{ In this case:} \\ p=(152-147)/(147)\cdot100 \\ p=(5)/(147)\cdot100=(500)/(147) \\ p=\: 3.4\% \end{gathered}`

Which means that the percentage of change is 3.4%
