Hello there! So the speed goes up in 6 seconds, maintains for 8 seconds, and then holds for 20 seconds. When something is resting, the line stays straight horizontally for that 20 seconds. B and C are eliminated, because there is no break for C and B does not show the speed accurately. Really, the fish would speed up to 2.5 m/s in 6 seconds, then it maintains that speed, and slows down. D shows a constant speed, which the speed isn't constant, so D is out. A is the only one that represents the scenario properly. The answer is A.

Knowing you cannot simplify 6/25 any further, you now have your answer!
Hope this helps! <3
The variable assumes a decimal value, hence it is a rational number.
<h3>What are continuous and discrete variables?</h3>
- Continuous variables: Can assume decimal values, hence they are represented by rational numbers.
- Discrete variables: Assume only countable values, such as 1, 2, 3, …, hence they are represented by whole numbers, or even integers if it can be negative.
In this problem, the time assumes a value of 0.25, which is decimal, hence it is a continuous number, that is rational.

Answer:
3.5 meters
Step-by-step explanation:
- 1:4 = x:14 ; where x is the unknown length of A
- 1/4 = x/14 (Cross multiply)
- Giving us, 4×x = 14×1
- 4x = 14 (Divide both sides by co-efficient of x, which is 4)
- x = 14/4
- x = 3.5
- Therefore, the length of A is 3.5 meters.
