A parachutist's elevation changes by -91 ft in 13 seconds. What is the change in the parachutist's elevation each second?
Question content area bottom
To find the change in the parachutist's elevation each second, you would divide the change in elevation (-91 ft) by the number of seconds (13).
Change in elevation per second = (-91 ft) / (13 seconds)
Change in elevation per second ≈ -7 ft/second
To find the change in elevation per second, we need to divide the total change in elevation by the total time it took.
Given:
Change in elevation = -91 ft
Time = 13 seconds
To find the change in elevation per second, we divide the change in elevation by the time:
Change in elevation per second = Change in elevation / Time
Change in elevation per second = -91 ft / 13 seconds
Calculating this division, we get:
Change in elevation per second = -7 ft
Therefore, the change in the parachutist's elevation each second is -7 ft.
