Raman and Krishnan start moving towards each other from points A and B, 200 m apart from each other. After walking 60 metres, Krishnan takes a left turn and walks 20 metres, then he takes a right turn and walks 40 metres. He again takes a right turn and comes back on the path from where he started. Raman did not turn anywhere while walking. If Raman and Krishnan walk at the same speed, what is the distance between them now?
Explanation:
Krishnan covered a total distance of 60 + 20 + 40 + 20 = 140m. Because they walk at the same speed, Raman also walked 140m straight. Krishnan advanced 60 + 40 = 100m towards Raman's starting point. Raman advanced 140m towards Krishnan's starting point. Distance between them = Total distance (200) - (100 + 140) = |200 - 240| = 40 meters.
Amit traveled 15 km in a car, then took a left turn and traveled 5 km, then took a left turn and traveled 15 km. If he is now facing east, how far is he now from the starting point?
Explanation:
If two left turns (180° rotation) put him facing East, he must have started facing West. Path: 15km West, 5km South (left turn), 15km East (left turn). His final position is exactly 5km South of his starting point.
