Raghu starts from his home in his car and goes 8 km north, then 6 km east. After that goes 10 km to the right and then 4 km to the left, then 10 km to the north and finally 4 km to the right. In which direction is he from his starting point at this time?
Explanation:
Moves: 8 North, 6 East. Right (South) 10, Left (East) 4. North 10, Right (East) 4. Total North = 8 - 10 + 10 = 8. Total East = 6 + 4 + 4 = 14. Positive North and East means he is in the North-East direction.
A woman starts from a point and walks 15 m. Goes south. She turns left and walks 12 m. It moves Then she takes a right turn and walks 5 m. At the end of running, she turns and walks 20 m. It moves How far is he from the starting point?
Explanation:
She goes 15 m South, then 12 m East (left turn), then 5 m South (right turn). Total South = 20 m. When she turns and walks 20 m (implying a 180° turn to go North), the 20 m North cancels out the 20 m South. She is left exactly 12 m East of the starting point.
