Calculating Time Duration

How long is the journey? Train leaves 10:30, arrives 14:45. Duration: 14:45 - 10:30 = 4 hours 15 minutes. Method: Count hours first (10:30 to 14:30 = 4 hours), then count minutes (14:30 to 14:45 = 15 min). Total: 4h 15min. Another way: convert to total minutes. 10:30 = 630 min. 14:45 = 885 min. Difference = 255 min = 4h 15min.
