Final answer:
Before starting RAP or FDP, you need to have had 30 consecutive hours of rest within the past 168 hours.
Step-by-step explanation:
Before beginning any RAP or FDP, you should be able to look back 168 hours and find 30 hours of consecutive rest. This means that within the past 168 hours (7 days), there should be a period of at least 30 hours where you have not engaged in any activities or tasks.
