Answer:
108.75km
Step-by-step explanation:
please find attached the diagram
total displacement can be determined by using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
length of x =
20² + 40²
= 400 + 1600
2000
square root of 2000
= 44.72km
length of y
40² + 50²
1600 + 2500 = 4100
square root of 4100
64.03km
total displacement = 44.72 + 64.03 = 108.75
