Question

1. Anthony walks to the pizza place for lunch. He walks 1km east then 1km south east again.
What distance did he cover? What was his displacement

Answer 1

The answer is: distance is 3 km, displacement is 2.24 km.

Distance is total length: 1 km east + 1 km south + 1 km east again = 3 km
Displacement is the hypotenuse of the right triangles which sides are 1 km east and 2 km south. According to the Pythagorean theorem:
a² + b² = c²
1² + 2² = c²
1 + 4 = c²
5 = c²
c = √5
c = 2.24 km

Answer 2

Answer:

distance- 3 km

displacement- 2.24 km
