O An airplane left the airport at 08 45 and arrived at its destination at 16 48 on
the same day. How long was the flight?

Solution
You may use a timeline to help you.
From 09 00 to 16 00
= 7h
From 08 45 to 09 00 From 16 00 to 16 48
= 15 min = 15 min

10 11 12 13 14 15 16
Total flight time is 15 min + 7 h + 48 min = 7 h and 63 min
= 8 h and 3 min

The flight was 8 h 3 min long.
