Answer:
29.51m
Explanation:
Suppose you walk 11.2 m straight west and then 27.3 m straight north. How far are you from your starting point
Your distance from the starting point is your displacement
Using the pythagoras theorem
d² = (-11.2)²+(27.3)²
d² = 125.44+745.29
d² = 870.73
d = √870.73
d = 29.51m
Hence your distance from the starting point is 29.51m
