The statement that must be true about the two postal delivery workers is:
He is going slower and in a different direction during the first 10 minutes than in the last 10 minutes.
To determine which statement must be true about the two postal delivery workers, we can analyze the given information about their routes. Both workers travel from the post office to neighborhoods to deliver mail and then back to the post office.
The first statement suggests that the delivery worker is speeding up during the first 10 minutes and slowing down during the last 10 minutes. However, based on the given information, we cannot make any conclusions about the speed changes during specific time intervals.
The second statement states that the delivery worker is going faster and in a different direction during the first 10 minutes than in the last 10 minutes. Again, based on the information provided, we cannot deduce anything about changes in speed or direction during different time intervals.
The third statement claims that the delivery worker is going slower and in a different direction during the first 10 minutes than in the last 10 minutes. However, there is no evidence to support this claim in the given information.
Finally, the fourth statement suggests that the worker's acceleration increases during the first 10 minutes and decreases during the last 10 minutes. Since acceleration refers to changes in velocity over time, and the given information does not mention anything about velocity or acceleration, we cannot determine this statement to be true either.
Therefore, based on the information provided, we cannot conclude which statement must be true about the two postal delivery workers.
