Question

juanita is watering her lawn using the water stored in her rainwater tank. the water level in the tank drops 1/3 inch every 10 minutes she waters. what is the expected change in the tank's waster level after 2.25 hours

Answer 1

Fraction of tank drops in every 10 minutes  = 1/3 inches.

We need to find the expected change in the tank's water level after 2.25 hours.

Let us convert 2.25 hours in minutes.

1 hours = 60 minutes.

2.25 hours = 2.25 × 60 = 135 minutes.

We need to divide 135 by 10.

We get 13.5.

Now, we need to multiply 1/3 by 13.5, we get.

13.5/3 = 4.5 inches.

So, tank would drop 4.5 inches after 2.25 hours.
