On his fishing trip Justin takes the boat 4 km south. The fish aren’t biting so he goes 4 km back east. He follows a school of fish 4 km further north and then 3 km west. What distance did he cover? What was his displacement?

Distance = 15km

Displacement = 1km

Explanation:

the total distance covered is how far Justin has travelled =  4km + 4km + 4km + 3km

Total distance covered = 15km

To get the displacement, we will use the Pythagoras theorem. Find the diagram attached.

From the diagram, the displacement D is expressed as:

D = AC - BC

From the diagram

AC = 4km

BC = 3km

D = 4km - 3km

D = 1km

Hence his displacement is 1km

glen is correct.

step-by-step explanation:

glen is correct because when you multiply 4 * 2 = 8.

and 4 * 3 = 12.
