I need help with this question please i beg

The answer is 16m.

To find this, note we are only looking at the time between t=6 and t=10. In this time, the object moves from x=8 to x=16 until it turns around and moves back to x=8.

Looking at the distance, we see that we just add the absolute values of the change in x, getting abs(16-8) + abs(8-16) where abs means absolute value.

This gets the answer 8+8 which is 16.

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.
