Answer:
East Port Tier City is 11.5 hours ahead of Phoenix.
Step-by-step explanation:
Given that the city of Phoenix, Arizona is located in the UTC -7 time zone, while East Port Tier City is located at UTC +4.5, to determine the time difference between the two cities, the following calculation must be performed:
4.5 - (-7) = X
4.5 + 7 = X
11.5 = X
Thus, the time difference between Phoenix and East Port Tier City is 11.5 hours.
