• North-East of the starting point, 13 km

• South-East of the starting point, 13 km

Answer 1

North-East of the starting point, 13 km

Explanation:

From

AB = 30 - 8 - 10 = 12 km

BC = 26 + 19 - 40 = 5 km

Distance from starting point

AC = `sqrt(("AB")^2 + ("BC")^2)`

`= sqrt((12)^2 + (5)^2)` = 13 km

Direction is North-East
