Question

2.) A scuba diver is swimming 18 feet below the water's surface. The diver swims up slowly at 0.6 feet per second for 5 seconds and then swims up for 2 more seconds at 0.3 feet per second. What is the diver's new depth?

Answer 1

Answer:

The diver's new depth is 14.4 feet.

Step-by-step explanation:

Given:

A scuba diver is swimming 18 feet below the water's surface.

The diver swims up slowly at 0.6 feet per second for 5 seconds and then swims up for 2 more seconds at 0.3 feet per second.

Now, to find the diver's new depth.

As given,

Total depth = 18 feet.

Total distance covered:

$Distance\ covered = 0.6\times 5+0.3\times 2$

$Distance\ covered = 3+0.6$

$Distance\ covered =3.6$

Now, to get the new depth:

New depth = Total depth - distance covered.

$New\ depth=18-3.6$

$New\ depth=14.4\ feet.$

Therefore, the diver's new depth is 14.4 feet.
