Respuesta :

Answer:

C. The total distance is 105 kilometers and the total displacement is 15 kilometers east.

Explanation:

The main difference between distance and displacement is that: distance is a measure of the total length traveled along the road, the displacement only takes into account the length between the initial (departure) and final (arrival) position.

So the boat traveled 105 km, but the displacement between the start and finish point is only 15 km.
