Final answer:
To determine the duration of Anjali's train journey from Beijing to Shanghai, the departure time (07:25) was subtracted from the arrival time (13:15), resulting in a travel time of 5 hours and 50 minutes.
Step-by-step explanation:
To calculate the duration of Anjali's train journey from Beijing to Shanghai, we need to subtract the departure time from the arrival time. The train departs at 07:25 and arrives at 13:15.
First, convert both times into the 24-hour format for ease of calculation: 07:25 AM is simply 07:25, and 13:15 PM is already in 24-hour format.
Now, subtract the departure time from the arrival time. Starting with the minutes: if we have 15 minutes arrival and subtract 25 minutes departure, we need to borrow 1 hour from the arrival hour since 15 is less than 25.
So 13:15 becomes 12:75 (since 60 minutes make up 1 hour). Now subtract the minutes: 75 - 25 = 50 minutes. Next, subtract the hours: 12 - 7 = 5 hours.
Therefore, the train journey takes 5 hours and 50 minutes.
