### Solution:

Concept- Using concepts of time, speed and distance with the help of basic conversion units the given question can be easily solved.
We are given the departure and arrival times of a plane at an airport.

$\mathit{Duration of flight}=\mathit{arrival time}-\mathit{departure time}$

To find the difference between the minute parts of the times, we subtract 23 from $60+10=70$
minutes as 1 hr = 60 min.
Therefore, the duration of the flight = .
Hence, the correct option is 2.
