A full lake is dropping at its constant rate, meaning it is unchanging over time.

After 4 weeks’ time, it already dropped 3 feet.

Now, let’s solve for the Unit rate based on the given data.

=> 3 feet in 4 weeks

=> Unit rate is 3 feet per 4 weeks

=> in 4 weeks there are (7 * 4) = 28 days

=> 3 feet / 28 days

=> the Unit rate is. 107 feet / day
