Arvin, the ant, is on a picnic table. He travels 30 cm eastward, then 25 cm northward, and finally 15 cm westward. What is total distance traveled by Arvin?

The total distance traveled by Arvin is 70 cm.

Explanation:

Distance and Displacement

A moving object constantly travels for some distance at defined periods of time. The total distance moved is the sum of each individual distance the object traveled. It can be written as:

dtotal=d1+d2+d3+...+dn

This sum is obtained independently of the direction the object moves.

The displacement only takes into consideration the initial and final points of the path defined by the object while it's moving. The displacement, unlike distance, is a vectorial magnitude and can be even zero if the object starts and ends the movement at the same point.

Arvin, the ant, moves 30 cm eastward, then 25 cm northward, and finally 15 cm westward. The total distance traveled is 30 cm+25 cm + 15 cm = 70 cm.

The total distance traveled by Arvin is 70 cm.
