To find the duration of the train journey from Hyderabad to Chennai, we can follow these steps:

### Step 1: Identify the start and end times
- **Start time:** 01:15 PM on Friday
- **End time:** 07:30 AM on Saturday

### Step 2: Calculate the time from the start time to midnight
- From 01:15 PM to midnight (12:00 AM) on Friday:
- From 01:15 PM to 12:00 AM is 10 hours and 45 minutes.

### Step 3: Calculate the time from midnight to the end time
- From midnight (12:00 AM) to 07:30 AM on Saturday:
- This is 7 hours and 30 minutes.

### Step 4: Add the two durations together
- Total duration = Time from start to midnight + Time from midnight to end
- Total duration = (10 hours 45 minutes) + (7 hours 30 minutes)

### Step 5: Perform the addition
1. Add the hours:
- 10 hours + 7 hours = 17 hours
2. Add the minutes:
- 45 minutes + 30 minutes = 75 minutes
3. Convert 75 minutes into hours:
- 75 minutes = 1 hour and 15 minutes

### Step 6: Combine the total hours and minutes
- Total duration = 17 hours + 1 hour and 15 minutes = 18 hours and 15 minutes

### Final Answer:
The duration of the journey is **18 hours and 15 minutes**.
