1 hr 47 min
B
2 hr 47 min
C
1 hr 20 min
D
2 hr 20 min

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.

Departure time = 1 : 23 P . M . = 1 hr 23 \min

Arrival Time = 4 : 10 P . M = 4 hr 10 \min

Duration of flight = arrival time - departure time

= 4 hour 10 minute - 1 hour 23 minute

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 =

3 hr 70 \min - 1 hr 23 \min = 2 hr 47 \min

.
Hence, the correct option is 2.
