0.23 s.

Explanation:

Let's investigate the given positions.

We are asked to find the time it takes from x = 0 to x = - A. The part goes in the + x direction, so it will first go + A, then it turns back and goes to - A. The time it takes for this trajectory is 3T/4, where T is the period.

T = 1/f = 0.3125.

So the time it takes from x = 0 to x = - A is 0.23 s.
