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-

The estimated time of arrival at the destination Airport will be 1730 PST.

Explanation:

Given:

Time at which flight departs from airport = 1615 MST

Duration of flight the reach destination airport = 2 hour 15 minute.

We need to find the estimated time of arrival at the destination airport.

Solution:

Now Given:

The Destination Airport is located in Pacific standard time zone.

Now first we will find the Arrival of flight at destination airport in MST.

Now we can say that;

Arrival of flight at destination airport will be equal to sum of Time at which flight departs from airport and Duration of flight the reach destination airport.

Arrival of flight at destination airport in MST =

Now We know that;

Mountain standard time is 1 hour ahead then Pacific Standard time.

Now Arrival of flight at destination airport in MST = 1830 MST

Arrival of flight at destination airport in PST = 1730 PST.

Hence The estimated time of arrival at the destination Airport will be 1730 PST.
