A hot-air balloon is 1550 feet off the ground and its altitude is slowly changing at a constant rate of −712 feet per second.
2 answers:
Building and solving an equation to model the situation, it is found that it will take 1.52 seconds for the balloon to drop to below 465 feet.
- The initial height is of 1550 feet.
- Each second, the height decreases by 712 feet.
Hence, the equation that models the height of the balloon after t seconds is:
To find how many seconds, s, will it take for the balloon to drop to below 465 feet, we have to find <u>t for which h(t) < 465</u>, hence:
It will take 1.52 seconds for the balloon to drop to below 465 feet.
