Answer 1

See Explanation

Explanation:

The question is incomplete. However, a possible question is "calculate the depth of the lake after certain number of hours (say 2 hours)"

Given

`Rate = (1)/(4)ft/hr`

`Depth = 279ft`

First, we calculate the depth receded.

If the rate is 1/4ft per hour

Then

The Depth receded in 2 hours is:

`Receded = (1)/(4) * 2`

`Receded = (2)/(4)`

`Receded = 0.5ft`

The new depth is then calculated as:

`New\ Depth = 279ft - 0.5ft`

`New\ Depth = 278.5ft`
