Answer: 14 minutes
Step-by-step explanation:
To find out how long it will take for the hot air balloon to change its elevation by -315 feet, you can use the formula:
Time = Change in elevation / Rate of descent
Given:
- Change in elevation = -315 feet (negative because it's descending)
- Rate of descent = 22.5 feet per minute
Substitute the values into the formula:
Time = -315 feet / 22.5 feet per minute
Time = -14 minutes
Since time cannot be negative in this context, the negative sign indicates that the balloon is descending. Therefore, it will take approximately 14 minutes for the balloon to change its elevation by -315 feet.
