Question
Vikas took a bus from a bus stop. The bus travelled 50 m
towards the west. Then, it took a right turn and travelled 70 m. Then, it took a left turn and travelled 15 m. Then, it took a left turn and travelled 30 m. Then, it took a left turn and travelled 35 m. Then, it took a right turn and travelled 10 m. Finally, it took a left turn and travelled 30 m to reach the school. How far and in which direction is the bus stop from the school? (All turns are 90-degree turns only)Solution
Bus moves 50 m west Position: (-50, 0) Takes a right turn (north) and travels 70 m Position: (-50, 70) Takes a left turn (west) and travels 15 m Position: (-65, 70) Takes a left turn (south) and travels 30 m Position: (-65, 40) Takes a left turn (east) and travels 35 m Position: (-30, 40) Takes a right turn (south) and travels 10 m Position: (-30, 30) Takes a left turn (east) and travels 30 m  Position: (0, 30) → This is the school. Distance and Direction from the Bus Stop (0,0) to the School (0,30): Distance = 30 30 m Direction = North Answer: 30 m, North
