Riemann sum problem that i need solved! (the problem is attached as a screenshot)

You need to find the exact distance, so a Riemann sum isn't exactly needed but can be used.

The sum-free way to do this is to integrate over , assuming a starting position of .

The question says to use a graph (which isn't given), but the idea would have been to find the area under the curve , which would be a triangle whose area would be easy to find.

i think the correct option is the second option.
