Answer:

Step-by-step explanation:
Subtract 7x from 8x.
Move all terms not containing x to the right side of the equation.
Add 9 and 2.
The unit rate in minutes per meter for filling the given aquarium to a depth of 2/4 meters will be 8 minutes per meter.
We have,
Time taken to fill an aquarium to a depth of
m = 4 minutes,
So,
Time = 4 minutes,
And,
Depth =
m,
Now,
The unit rate in minutes per meter,
So,
We will Now convert given depth fraction,
i.e.
Depth =
= 0.5m,
So,
It takes 4 minutes to fill a half meter,
Then,
To fill a meter it will take =
= 8 minutes
So,
The unit rate in minutes per meter is 8 minutes per meter.
Hence we can say that the unit rate in minutes per meter for filling the given aquarium to a depth of 2/4 meters will be 8 minutes per meter.
