Jenna throws a stone off a pier and into the ocean.  The graph models how the height of the stone, above sea level, changes over time.

During what period of time was the stone falling toward the water?

here is the link photo:

0 seconds to 0.5 seconds

0 seconds to 1 second

0 seconds to 1.5 seconds

0.5 seconds to 1.5 seconds

Re: math

It depends on how you interpret "toward the water".

The x-axis represents time in seconds.

The graph shows the stone rising from 0 to 0.5 seconds and then falling the rest of the time.

If "toward the water" means from the time it left her hand, then the answer is 0 to 1.5 seconds.
If "toward the water" means the stone's downward path, after rising at first, then the answer is 0.5 to 1.5 seconds.
