My father went to a shop from home which is located at a distance of 250 m on a straight road. On reaching there, he discovered that he forgot to carry a cloth bag. He came home to take it, went to the shop again, bought provisions and came back home. How much was the total distance travelled by him? What was his displacement from home?
1000 m
0 m
Explanation
According to the textbook, total distance travelled is the sum of all distances covered along the path, while displacement is the distance between the starting and stopping positions. The father travels 250 m four times, giving a total distance of 1000 m. Since his starting and stopping positions are the same (home), his displacement is 0 m, just like the example of Sarang in the text where returning to the starting point results in zero displacement.
