So 5/3 is not an irrational number, it's rational.
The answer is d. because the equation goes in a line and linear equations have ALWAYS have a constant speed rate.

Find critical points by setting derivative equal to 0.
Derivative of polynomial is found by multiplying coefficient by exponent, then subtracting 1 from exponent.
f'(x) = 5x^4 - 30x^2 + 9 = 0
This is in quadratic form, use quadratic formula to find x^2
Let x represent number of hours after noon.
We have been given that Sara starts at noon and walks at a speed of 4 miles per hour. So distance covered by Sara in x hours would be .
We are also told that Eddie leaves the same place an hour later. This means that Sara will be 4 miles ahead of Eddie as Sara will travel 4 miles in 1 hour.
As Eddie walks in the same direction at a speed of 5 miles per hour. So distance covered by Eddie in x hours would be .
Total distance covered by Sara when Eddie will start would be .
Now we will equate distance covered by both in x hours as:
Let us solve for x.
Since x represents number of hours after noon, so 4 represents 4 hours after noon.
Therefore, Eddie will catch up with Sara at 4:00 pm and option D is the correct choice.
I’m pretty sure that it is “the same area as”
