Answer:
20 days
Step-by-step explanation:
899- 225= 674
674÷ 35= 19.257....
which you would round it up to 20 because he would have to work the extra day because you need more than less.
Consider the attached ellipse. Let the sun be at the right focus. Then perihelion is at right vertex on the x-axis and aphelion is at the left vertex on the x-axis.
The distances:
- from perihelion to the sun in terms of ellipse is a-c;
- from aphelion to the sun in terms of ellipse is a+c.
Then

Add these two equations:
and subtract first equation from the second:
Note that
thus

The equation for the planet's orbit is

In the original set of numbers, the median is six
But, if six was added to the set, then the median would be six
So the median wouldn't decrease at all
Nine and ninety-eight hundreths
