A​ parachutist's elevation changes by minus

140
ft in 14

seconds. What is the change in the​ parachutist's elevation each​ second?

1 answer

To find the change in elevation per second, we need to divide the total change in elevation by the total time taken.

Change in elevation per second = Total change in elevation / Total time

Given: Total change in elevation = -140 ft, Total time = 14 seconds

Change in elevation per second = -140 ft / 14 seconds

Change in elevation per second = -10 ft/second

Therefore, the change in the parachutist's elevation each second is -10 ft.
