Question
Riya starts from her school towards East.She walks 20m and then she turns left and walks 5m to buy chocolate from ashop. Then she walks 25m after taking a left turn from the shop and then againtakes a left turn and walks 5m.How far is Riya from her school?5m20m10m15m
Solution
Riya starts from her school and walks 20m towards the East. Then she turns left (which would be towards the North) and walks 5m to buy chocolate from a shop. From the shop, she takes another left turn (which would be towards the West) and walks 25m. Finally, she takes one more left turn (which would be towards the South) and walks 5m.
Now, to find out how far Riya is from her school, we need to consider her displacement in the East-West direction and the North-South direction.
In the East-West direction: She initially walks 20m East, then 25m West. So, her total displacement in the East-West direction is 20m - 25m = -5m. The negative sign indicates that she is 5m to the West of her school.
In the North-South direction: She walks 5m North, then 5m South. So, her total displacement in the North-South direction is 5m - 5m = 0m. This means she is neither to the North nor to the South of her school.
So, Riya is 5m to the West of her school. Therefore, she is 5m away from her school.
