It takes 9 minutes to fill an empty aquarium of a depth of 3/5 meters. What is the unit rate in minutes per meter?
GarryVolchara [31]

Answer:

<h2>The rate is 15 minutes per meter.</h2>

Step-by-step explanation:

It takes 9 minutes to fill a depth of \frac{3}{5} meters.

Filling  \frac{3}{5} meters take 9 minutes time.

Filling 3 meters of the aquarium takes 5\times9 = 45 minutes time (Multiplying by 5 both the numbers).

In order to<u> fill 1 meter of the aquarium it will take </u>\frac{9\times5}{3} = 15<u> minutes</u> (Dividing by 3 both the numerical values).
