During a scuba dive, Lainey descended to a point 26 feet below the ocean surface. She continued her descent at a rate of 26 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 68 feet below the ocean surface. Use t to represent the variable for the minutes Lainey can continue to descend.
To find the number of minutes Lainey can continue to descend, we want to keep track of her depth below the ocean surface. Let's represent the number of minutes she can continue to descend by the variable t.
Lainey starts at a depth of 26 feet below the ocean surface and continues descending at a rate of 26 feet per minute. This means her depth below the surface can be calculated as 26 + 26t, where t represents the number of minutes she has been descending.
We want to find the number of minutes Lainey can descend without reaching a depth of more than 68 feet below the ocean surface. This can be represented by the inequality:
26 + 26t ≤ 68
Now we can solve this inequality to find the possible values of t.
how far? <(68 - 26) = </= 42 feet more
distance = speed * time
26 t </= 42
t </= 1.62
