Question

On their first day, researchers explore a part of the ocean floor that is 60 feet below sea level. This depth can be represented by the integer -60. On their secon dive, researchers explore a deeper depth.

Write an inequality that represents the possible depth, d, of the researchers' second dive.

Answer 1

d < - 60

Explanation:

Given that:

Depth, d of ocean floor on first dive = 60 feets below sea level = - 60

Depth, d explored on second dive is deeper than that of fist dive

Hence, possible depth, d, explored on second dive can be represented by the inequality ;

d < - 60
