If a ceiling balloon rises at 402 feet per minute, what will the ceiling (base of the clouds deck) of an
overcast deck of stratus clouds 5000 feet thick be if the balloon disappears into the clouds in 14
minutes? Enter only the numeric portion of your answer. For example, if you calculate the answer to be
3500 feet, enter only 3500. Do not enter the word feet in your answer. ✔✔5628 (margin of error +/- 10)
