Question

A plane left an airport at $1:23$ P.M. It arrived at its destination in the same time zone at $4:10$ P.M. How long was the flight?

• A. $1$ hr $47$ min
• B. $2$ hr $47$ min
• C. $1$ hr $20$ min
• D. $2$ hr $20$ min

Answer 1

The correct option is B $2$ hr $47$ min

We subtract the arrival time and the departure time we get the time of flight.

$\therefore$ $4:10-1:23$ = $2:47$

That is $2$ hr $47$ min.
