Walking 6 km north, then 8 km east. How far are you from the start?
A12 km
B10 km
C14 km
D8 km
Answer & Solution
Correct answer: A. 12 km
1. The path forms a right triangle with legs 6 and 8.
2. The straight-line distance is the hypotenuse.
3. d = sqrt(6^2 + 8^2) = sqrt(36 + 64) = sqrt(100) = 10.
4. So you are 10 km from the start.
