To arrive by 9:15 with 15 minutes travel, what is the latest time you should leave?

Explanation:
The key idea is to find the latest departure time that still lets you arrive by the specified time. If you must arrive by 9:15 and the trip takes 15 minutes, you subtract 15 minutes from 9:15. That leaves 9:00 am. Leaving at 9:00 am gets you there exactly at 9:15. If you leave any later, you’d arrive after 9:15, which misses the target. Leaving earlier is fine but wouldn’t be the latest possible departure.
