Given radius is 1.45 km
Now as they trevelled two third of the circle then if we will join the start point as well as end point we will get a chord to the circular path. The chord length AB will be the displacement.
This chord will substain 120° at the center hence we get an triangle whose 2 sides are radius and one is chord and angle between radius is 120° as shown in figure
Hence displacement is 2.5115 km
I am not solving for direction as u have already marked that correct

You are at a circular lake with radius 30 km, centered at the point (0,0). You want to travel from (30, 0) to (-30,0). You will row from (30, 0) in a straight line to a point on the shore that is angle 0 radians around the lake from where you started, and then you will walk the rest of the way along the circular shore to (-30,0). Your rowing speed through the lake is 6 km/h, and your walking...
