Final answer:
There is not enough information provided to determine whether Jacob should take his normal route or the alternate route to work. He should assess commute times and traffic patterns to make an informed decision.
Step-by-step explanation:
The question asks whether Jacob should take his normal route or the alternate route to work in order to be on-time or early. The provided information does not include specific details about the duration or reliability of Jacob's normal route compared to the alternate route. Therefore, not enough information is given to determine which route Jacob should take. Jacob should plan his route by considering factors such as traffic patterns and any known delays, perhaps by performing trial runs or collecting commute time data to make an informed decision.
