12. Time and Motion

Lesson

When we're calculating how long a flight takes, we need to consider the local time in both cities. Similarly, if we want to know the local time in the departure/arrival city, we need to consider the time in one city and the flight time and then adjust the time based on time zones.

A plane left airport A at $8$8:$30$30 pm on Tuesday and landed at airport B at $9$9:$00$00 pm (local time) on the same day.

If airport B is $19$19 hours behind airport A, how long did the trip take?

When the time is $5$5:$23$23 pm in Honolulu, it is $10$10:$23$23 pm in Miami. You take 19 hours to travel from Honolulu to Miami.

If you leave at $4$4:$50$50 pm on Sunday:
