Exel rides his bike 21 km west and then 18 km north how far is he from his starting point?

Answers

Displacement = sqrt(x^2 +y^2)
where x is the displacement in the horizontal axis and y is the displacement in the vertical axis
displacement = sqrt(x^2 +y^2) 
=sqrt(5^2 +8^2)
=9.434 km

Step-by-step explanation:

bakit bigla ka nalang nan jaan

d = √3h/2

h=2d^2/3

h=2(5m)^2/3

h=16.67m

d=√3(16.67)/2

d=5m

He is 39 km from his starting point

Step-by-step explanation:

1st displacement = 21 km

2nd displacement = 18 km

Total displacement = 1st displacement + 2nd displacement

Total displacement = 21 km + 18 km

Total displacement = 39 km
