Answer

The required expression for the depth is feet.

The depth after 1.3 minutes is 71.5 feet.

Step-by-step explanation:

Let d be the depth of the sea below the surface of the water.

The rate of descending or the rate of increasing the depth, feet/min.

Since, the rate is constant, so,

If the diver reaches the depth, , in time, . So,

So, for feet/min, the required expression for the depth is feet.

After time t= 1.3 minutes.

The depth, feet.
