Time of a Descent
A submarine traveling at 9.0 mph is descending at an angle of depression of [c]o. How many minutes, to the nearest tenth, does it take the submarine to reach a depth of 1[b]0 feet? Be sure to include a sketch. Use the following conversion: 1 mile = 5280 ft. My PIN : 25746 [a][b][c][d][e]
Note: if [c]=7, then [c]o=7o, and if [b]=4, then 1[b]0=140 feet
