Final answer:
The question regarding the length of Route A and Route B for an employee's walk from work to home cannot be answered without specific distance information on both routes. The provided examples do not relate to the original question, so no accurate answer can be given based on the current data.
Step-by-step explanation:
The question provided does not contain sufficient information to calculate the difference in length between Route A and Route B for an employee walking from work to home. To accurately answer which route is longer and by how much, one would need specific information about the distances of Route A and Route B. In mathematics, such problems typically involve comparing measured lengths or calculated distances to determine which is greater.
Looking at the provided information, there are examples related to different distance measurements and average speed calculations, but nothing that specifically correlates to the original question about Route A and Route B. Therefore, without additional context or data about these routes, we cannot determine which route is longer, making it impossible to select from the given answer choices (a, b, c, or d).
