Question

A person walks 1 mile every day for exercise, leaving her front porch at 9:00 am. and returning to her front porch at 9:25 am. What is the total displacement of her daily walk

Answer 1

Answer: 0

Explanation:

Given that:

Distance walked per day = 1 mile

Starting position = front of house

Final position = front of house(initial position).

In other to aid understanding; Displacement simply refers to the shortest or least distance measured from an individual's initial position to his final point.

Here,

Assume, front of house = point A

Then , initial position = point A (front of house)

Final position, = point A (front of house)

Hence, the shortest distance between final and initial positions is :

Point A - Point A = 0

Since, starting point is the same as the final point, then Displacement = 0
