Problem
When it is 3:00 p.m. in Victoria, it is 6:00 p.m. in Timmins. Stefan’s flight departed at 6:00 a.m. local Victoria time and arrived at 4:00 p.m. local Timmins time. How long, in hours, was his flight?
Solution 1
From the first sentence of the problem, we can realize that Timmins is 
hours ahead. This means that 
am in local Victoria time is the same thing as 
am in local Timmins time.
hours after am is 
pm, and 
hours after that is 
pm, so his flight was 
hours long.

Solution 1.1
We can also use the time conversion, but convert Timmins time to Victoria time to solve the problem.
pm in local Timmins time would be 
pm in local Victoria time.
hours after am is pm, and 
hour after that pm, so his flight was 
hours long.
