Atoy robot moved from a starting point, traveling in a straight line at different speeds and then turning around and returning to the starting point at different speeds. what is the total distance that the toy robot traveled?

The total distance is equal to the change in total position of the person, but the displacement of the person is zero.

Explanation:

The distance is the total change in the positions of the toy robot. it is having only magnitude and it is a scalar quantity.The displacement is the difference between the final and initial position of the toy robot. it is a vector quantity having magnitude and directionSince the distance is the change in positions, so the magnitude of the distance will be equal to the up and down distance covered.If the toy robot travels in a straight line path and returns back to its original location, the magnitude of the distance and displacement doesn't depend on the speed of the toy robot.
