alleryTwo boys A and B start at point P. A goes 5 km north then 12 km east. B goes 5 km south then 12 km west. Distance between them?
A13 km
B17 km
C26 km
D34 km
Answer & Solution
Correct answer: C. 26 km
1. A ends at (12, 5) from P.
2. B ends at (-12, -5) from P.
3. Difference = (24, 10).
4. Distance = sqrt(24^2 + 10^2) = sqrt(576 + 100) = sqrt(676) = 26.
5. So they are 26 km apart.
