Question

It takes 4 minutes to fil an empty aquarium to a depth of 2/4 meters. what is the unit rate in minutes per meter ? write your answer in simplest form.

Answer 1

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  $\frac{2}{4}$ m = 4 minutes,

So,

Time = 4 minutes,

And,

Depth =  $\frac{2}{4}$ m,

Now,

The unit rate in minutes per meter,

So,

We will Now convert given depth fraction,

i.e.

Depth =  $\frac{2}{4}$ = 0.5m,

So,

It takes 4 minutes to fill a half meter,

Then,

To fill a meter it will take = $\frac{4}{\frac{2}{4} }$ = 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.
