A submersible is a type of underwater vessel. Suppose a submersible starts at a depth of 40 feet below sea level, represented by β40 feet. The table shows the submersible's change in depth from one minute to the next.
Time and Depth of Submersible
2:15 p. m. 2:16 p. m. 2:17 p. m. 2:18 p. m.
β40 feet 180 feet lower 175 feet lower 185 feet lower
Answer the questions to find the depth of the submersible after 3 minutes.
1. Write and evaluate a subtraction expression to find the depth of the submersible at 2:16 p. m.
2. Write and evaluate a subtraction expression to find the depth of the submersible at 2:17 p. m.
3. Write and evaluate a subtraction expression to find the depth of the submersible at 2:18 p. m.
4. If the submersible dove straight down, what is the distance between the submersible's starting position at 2:15 and its position at 2:18? show your work
