Question

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?

Answer 1

Answer:

The rate is 15 minutes per meter.

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 fill 1 meter of the aquarium it will take $\frac{9\times5}{3} = 15$ minutes (Dividing by 3 both the numerical values).
