Question

During a scuba dive, Lainey descended to a point 20 feet below the ocean surface. She continued her descent at a rate of 20 feet per minute. Enter 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 93 feet below the ocean surface. Use t to represent the variable for the minutes Lainey can continue to descend.

Answer 1

Answer:

20t+20 ≤ 93

20t ≤ 73

t ≤ 73/20, or 3.65

Lainey can dive for 3.65 more minutes.
