Answer:
C, A and B
Step-by-step explanation:
Tank A holds 40 Liters and 5 fish.
- Volume per fish of Tank A
Tank B holds 100 Liters and 12 fish.
- Volume per fish of Tank B
Tank C holds 180 Liters and 23 fish.
- Volume per fish of Tank C
Therefore, the volume per fish from least to greatest is:
7.83, 8 and 8.33
These correspond to the tanks: C, A and B respectively.
For this case we have that the equation that describes the height is:
Where,
v: initial speed
c: initial height
Substituting values we have:
Then, to find the time, we use the quadratic formula:
Substituting values we have:
Rewriting:
We discard the negative root because we want to find the time.
We have then:
Answer:
D.
