It takes 4 and 1/2 minutes to fill an empty aquarium to a depth of 3/4 meters.

what is the unit rate per meter?

write as a fraction or mixed number in simplest form

To find the answer
Divide 4 1/2 minutes by 3/4 meters
First convert 4 1/2 to an improper fraction, which is 9/2
Then divide it, or cross-multiply it with 3/4
(9/2) / (3/4) or (9/2) * (4/3)
= 36/6
Which equals 6
So the answer is
1 meter every 6 minutes
Or if you want it the other way around
1/6 meters per minute
