Adam, Ben, Carl, and David all left this morning for vacation. All left in separate cars, headed for the same destination. Adam leaves first, followed by Ben, then Carl, and finally David. Adam leaves home at 4:31 and arrives at 8:12; Ben leaves at 5:22 and arrives at 9:20; and Carl leaves at 6:13 and arrives at 10:18. If David leaves home at 7:41 and his time of arrival follows the same pattern as each of his friends, what time did he arrive at the vacation spot?
