A drone flies 24 km towards the south, then 7 km towards the west. Its distance from the launch point is how many km?
The drone is 25 km from the launch point. The southward and westward legs are perpendicular, so the distance is √(24² + 7²) = √625 = 25 km. Adding the legs to get 31 km would be wrong.
- A31
- B17
- C26
- D25Correct
Explanation
South and west are perpendicular. Distance = √(24² + 7²) = √(576 + 49) = √625 = 25 km. The value 31 comes from adding the legs rather than applying Pythagoras.
Did you get it right without looking?
One question tells you little. A timed set on Direction Tests shows your real accuracy, how long you take and where you lose marks.
