Answer 1

Step-by-step explanation:

We are told that the rate at which the pump dumps the pollutant per day to be

`(√(t))/(15)`

To solve the question, let us assume that t is the number of days

So, to find the amount dumped after 3 days, we will put t =3 into the equation

`(√(3))/(15)=(1.732)/(15)=0.11547`

Therefore, the answer is 0.115
