Question

6. An elevator steadily descends 500 feet in 20 seconds. How would you express the change in the elevator's height per second?

Answer 1

To express the change in the elevator's height per second, you would divide the total change in height (500 feet) by the total time it took for the change to occur (20 seconds).

So, the change in the elevator's height per second would be 500 feet / 20 seconds = 25 feet per second. This means that the elevator is descending at a rate of 25 feet per second.
