Question

An aircraft departs an airport in the Central Standard Time zone at 0845 CST for a 2-hour flight to an airport located in the Mountain Standard Time zone. The landing should be at what Coordinated Universal Time?

a) 1445 UTC
b) 1345 UTC
c) 1245 UTC
d) 1545 UTC

Answer 1

The landing should be at 0445 UTC (option c).

Step-by-step explanation:

To determine the landing time in Coordinated Universal Time (UTC), we need to account for the time difference between the Central Standard Time (CST) and Mountain Standard Time (MST) zones. The CST is 6 hours behind UTC, while MST is 7 hours behind UTC.

Given that the flight is 2 hours long, the landing time in MST would be 0845 CST + 2 hours = 1045 CST. To convert this to UTC, we subtract the time difference between CST and UTC: 1045 CST - 6 hours = 0445 UTC.

Therefore, the landing in Coordinated Universal Time (UTC) would be at 0445 UTC (option c).
