A hot-air balloon is 1200 feet off the ground and its altitude is slowly changing at a constant rate of −7 1/2 feet per second.

How many seconds, s, will it take for the balloon to drop to below 3 1/0 feet?

Drag and drop a symbol and value to correctly complete the solution to this inequality.

Answer 1

Answer: s is
`> 118 (2)/(3).`

Explanation:

The air balloon will have to fall more than 890 feet for it to reach an elevation below 300 feet. It falls at a rate of 7.5, so 890/7.5=118.6666666666, which is 118 and 2/3. The answer is positive because time can never be negative.
