A submarine traveling at 9.0 mph is descending at an angle of depression of 7 degrees. How many minutes, to the nearest tenth, does it take the submarine to reach a depth of 13]0 feet? Be sure to include a sketch. Use the following conversion: 1 mile = 5280 ft.

Note: if 7=7, then 7 degrees=7 degrees, and if 3=4, then 130=140 feet
