Question

During a scuba dive, Lainey descended to a point 16 feet below the ocean surface. She continued her descent at a rate of 15 feet per minute. Write an inequality you could solve to find the number of minutes she can continue to descend if she does not want to reach a point more than 91 feet below the ocean surface. Use the variable t for time.

Answer 1

We can write the inequality as:

16 + 15t ≤ 91

where t represents the time in minutes.

Here you go!
