Question

Each second for 7 seconds, an elevator descends 5 feet. Find the total change in elevation.

Answer 1

Answer: There is total change in elevation of 35 feet.

Step-by-step explanation:

Since we have given that

Each second for 7 seconds, an elevator descends 5 feet

Number of seconds = 7 seconds

Length an elevator descends = 5 feet

So, total change in elevation would be

$7\times 5\\\\=35\ feet$

Hence, there is total change in elevation of 35 feet.
