An elevator travels up and down. The vertical position of the elevator in meters over time is shown below what is the displacement of the elevator between 8s and 20s?

What is the distance traveled by the elevator between 8s and 20s

The displacement is

-27m

The distance traveled is

27m

Dont listen to the other guys they are wrong

Explanation:

Well you see the elevator starts at 12m and 8s and moves down to 0mat 16s, traveling at a distance of 12m

The Elevator starts at 0m at 16s and moves down to -15m at 20s traveling a distance of 15m

So afterwards what you do is find the distance between 8 and 20 so do this equation

12m + 15m = 27m

So that gives you

-27

27

HOPE THIS HELPS!!!

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
