A parachutist's elevation changes by -99 ft in 9 seconds. What is the change in the parachutist's elevation each second?
The change in elevation each second can be calculated by dividing the change in elevation by the time it took to change.
Change in elevation each second = Change in elevation / Time
Change in elevation = -99 ft
Time = 9 seconds
Change in elevation each second = -99 ft / 9 seconds
Change in elevation each second = -11 ft/second.
Therefore, the parachutist's elevation changes by -11 ft each second.
To find the change in the parachutist's elevation each second, we need to divide the total elevation change by the total time taken.
The total elevation change is -99 ft and the total time taken is 9 seconds.
So, the change in the parachutist's elevation each second is calculated as:
Change in elevation per second = Total elevation change / Total time
Change in elevation per second = -99 ft / 9 seconds
Change in elevation per second = -11 ft/second
Therefore, the change in the parachutist's elevation each second is -11 ft/second.
