Aboy runs 30 m east, 40 m north, 50 m west. what is his net displacement?

Net displacement, d = 44.72 meters

Explanation:

In the attached figure, OA shows the net displacement.

Distance 1, d₁ = 30 m

Distance 2, d₂ = 40 m

Distance 3, d₃ = 50 m

Displacement of an object is equal to the shortest distance covered by an object. Here, the net displacement of the person can be calculated as :

d = 44.72 meters

So, the net displacement of the boy is 44.72 meters. Hence, this is the required solution.

0.19 m/s and 0.45 m/s

what is the actual question though?
