1. Calculamos a distância entre os pontos A(-5, 2) e B(0, 2):
d_{AB} = \sqrt{(0 - (-5))^2 + (2 - 2)^2}
d_{AB} = \sqrt{(5)^2 + (0)^2}
d_{AB} = \sqrt{25}
d_{AB} = 5 \text{ km}
2. Calculamos a distância entre os pontos B(0, 2) e C(4, 5):
d_{BC} = \sqrt{(4 - 0)^2 + (5 - 2)^2}
d_{BC} = \sqrt{(4)^2 + (3)^2}
d_{BC} = \sqrt{16 + 9}
d_{BC} = \sqrt{25}
d_{BC}=5\text{ km}
3. Somamos as duas distâncias para obter a distância total percorrida:
d_{total} = d_{AB} + d_{BC}
d_{total}=5\text{ km}+5\text{ km}
d_{total}=10\text{ km}
