The document discusses calculating the amount of water leaked from 0 to 3 minutes using an integral. It states that multiplying the integral by 1 does not change the function but is useful. The integral of the leaking rate function from 0 to 3 minutes gives 16/3 gallons leaked in the first 3 minutes.

1. Amount Leaked =
The integral from 0 to 3 of the function that models the rate at which
water is leaking will give the definite value of the amount of water
that is leaked from 0 to 3 minutes.

2. Amount Leaked =
Since we canʹt use calculators we can
antidifferentiate this using substitution.
Multiplying by 1 does not change the function but it is rather useful.
