Given the code fragment:ZonedDateTime depart = ZonedDateTime.

Given the code fragment:

ZonedDateTime depart = ZonedDateTime.of(2015, 1, 15, 3, 0, 0, 0, ZoneID.of(“UTC-7”));

ZonedDateTime arrive = ZonedDateTime.of(2015, 1, 15, 9, 0, 0, 0, ZoneID.of(“UTC-5”));

long hrs = ChronoUnit.HOURS.between(depart, arrive); //line n1

System.out.println(“Travel time is” + hrs + “hours”);

What is the result?
