Question

An aircraft departs an airport in the mountain standard time zone at 1615 MST for a 2-hour 15-minute flight to an airport located in the Pacific standard time zone. The estimated time of arrival at the destination airport should be:________.

A) 1630 PST.
B) 1730 PST.
C) 1830 PST.

Answer 1

B. 1730 PST

Step-by-step explanation:

First it is important to know that the flight lasted for 2 hours and 15 minutes, hence the first thing to do in this case is to add the duration of flight to the time of departure.

Time of departure = 1615 MST

Flight duration = 2:15

Hence we get 18:30 MST

Then we convert MST to PST by subtracting 1

1830 -1.00 = 1730 PST
