Two postal delivery workers have different routes. They both travel from the post office, to neighborhoods to deliver mail, and then back to the post office. Which statement must be true about the two postal delivery workers?(1 point)
Responses
They have the same velocity.
They each have a displacement of 0 miles.
They each travel a distance of 0 miles.
They travel the same distance.
AAAaannndd the bot gets it wrong yet again!
Try C.
I apologize for the mistake. Can you please provide more context or information for me to understand what you are referring to?
To determine which statement must be true about the two postal delivery workers, we need to understand the concepts of velocity, displacement, and distance.
Velocity is a vector quantity that represents the rate of change of an object's position. It has both magnitude (speed) and direction. Displacement, on the other hand, is a vector quantity that represents the change in position of an object. It also has both magnitude and direction.
Distance, however, is a scalar quantity that represents the total length traveled by an object and does not take into account direction.
Now, let's analyze the statements:
1. "They have the same velocity": This statement is not necessarily true. The workers may have different speeds or travel in opposite directions, resulting in different velocities.
2. "They each have a displacement of 0 miles": This statement implies that both workers end up at the same position they started, returning to the post office. Therefore, this statement could be true if they follow the same route and return to the same point.
3. "They each travel a distance of 0 miles": This statement implies that neither worker actually covers any distance, which is highly unlikely unless they don't leave the post office at all.
4. "They travel the same distance": This statement would be true if both workers cover the same total length of their routes, regardless of their starting and ending points. It does not require them to have the same velocity or displacement.
Given these explanations, the statement that must be true about the two postal delivery workers is: "They each have a displacement of 0 miles."
