Find the distance, in meters, a particle travels in its first 10 seconds of travel, if it moves according to the velocity equation v(t)= 49 − 9.8t (in meters/sec).

Question

I got 980 meters, but for some reason that isn't an option. I'm so sure that the answer is 980, can someone tell me if I'm right, or wrong, please? Thank you!

It looks like it moves 490 m away, then 490 m back
so either the distance traveled is 980 or 0 depending on what they mean by distance

We've been learning about the difference of distance from displacement, and I know it would be 0 if they were asking for displacement, but they're asking for distance. 0 is an option, so do you think they meant displacement but wrote the wrong thing? This is kinda stressful for me xD

I would mention this problem to your teacher.  But I'm guessing they meant displacement.  Or they made a mistake writing up the question.

I did that but my teacher isn't responding (I do online school). Thanks anyway ^u^

You can mention the next time you have a session.
