Her flight was 9 hours and 20 minutes.

Since 9 A.M. Karachi time is the same as 5 A.M. Warsaw time, we can take the time on her watch, Warsaw time, and subtract 4 to get the Karachi time.

Her watch said she left at 9:40 A.M. This is Warsaw time.

9:40 - 4 = 5:40 Karachi time.

Her flight took from 5:40 A.M. Karachi time to 3:00 P.M. Karachi time. This is 9 hours and 20 minutes.
