Final answer:
To meet the requirement of a one-hour one-way route with a 15-minute schedule, a bus must operate for a minimum of 12 hours daily. Therefore, the student's driving log should reflect a minimum of 12 hours to match this level of service.
Step-by-step explanation:
To solve the question presented, let's consider what the student's driving log requirement might mean in the context of the information given. The reference to a one-hour one-way route operating on a 15-minute schedule necessitates that a minimum number of buses are needed to keep the schedule without interruption. With a route duration of one hour and buses departing every 15 minutes, it's necessary to have a bus available at the starting point every 15 minutes to maintain the schedule. This results in the need for 4 buses in each direction to cover the full hour (15 minutes x 4 = 60 minutes).
Assuming that this service operates continuously for 12 hours or equivalently at half-power for a 24-hour period, one can calculate the minimum hours of operation required. Each bus would be completing 4 trips in a 12-hour period (12 hours / 3 hours per round trip = 4 trips). For a 24-hour operation at half-power, the calculation would yield the same result - 4 complete trips. Therefore, each bus would need to log at least 3 hours per trip, resulting in 12 hours of operation per bus, per day.
If the student's driving log requirement is to match a similar level of service and assuming they must meet the same operation conditions as a bus on this route, their log should reflect a minimum of 12 hours.
