So what can we deduce from that?
Assuming a chicken speed of 3m/s and a wolf speed of 5m/s. When they first start out, the chicken is going perpendicular to the wolf. So the wolf is gaining on the chicken at a rate of 5m/s.

As they end up closer and closer to heading in the same direction, the rate of closure drops down to 2 m/s, because the wolf is gaining at 5 m/s and the chicken is moving at 3 m/s.

Because of this, it's not possible that the wolf is gaining on the chicken at a constant speed. If so, your answer would be (distance separating)/(difference in speeds). So with the initial numbers of 200m / 2m/s that'd be 100 seconds they would travel. (or 300m chicken and 500m wolf)
