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

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
