From point P. a man rides a cycle 9 km towards East. Then, he rides the cycle 2 km towards North. From there, he rides the cycle 3 km towards East. Finally he rides the cycle 3 km towards North to a point Q. Then the distance between the points P and Q is (in km)
Consider P at the origin (0,0)
Then Q is located at (12,6)ย
Hence, distance between P and Q =ย $$\sqrt{\ \left(12-0\right)^2+\left(6-0\right)^2}$$ = 13
