Part 2: The next three hours The equipment in the helicopter is able to detect the submarine within a total distance of 750 feet. For each scenario, determine the maximum or minimum location for the other vehicle in order for the helicopter to detect the submarine; and write a mathematical sentence to show your thinking. Determine the ordered pairs for these additional hours and include them on your graph. At the end of the fourth hour, the helicopter remains at 250 feet. At the end of the fifth hour, the submarine returns to the same depth that it was at the end of the third hour. At the end of the sixth hour, the submarine descends to three times its second-hour position.
