Question

A parachutist's elevation changes by -35 ft in 5 seconds. What is the change in the parachutist's elevation each second?

Answer 1

7 feet per second

Explanation:

The change in elevation of the parachutist is -35 ft in 5 seconds. To find the change in elevation per second, we can divide the total change by the number of seconds.

Change in elevation per second = -35 ft / 5 seconds = -7 ft/s

So the parachutist's elevation changes by -7 ft/s each second.

It means the elevation of the parachute is decreasing by 7 feet per second.
