The displacement between point b and d is 145km because displacement is the shortest distance between two points.
The distance travelled from a to b and back is 10 km since total distance is the sum of all the journeys.
The displacement from b to d and back to b is 0km because we have moved back to our start position and so the displacement is 0 because it is the same as not moving at all.
