Answer

To find the total travel time of the train journey, we will break down the time intervals step by step.

### Step 1: Identify the Departure and Arrival Times
- The train departs from Delhi on **29th August 2019 at 16:30** (4:30 PM).
- The train arrives at its destination on **31st August 2019 at 08:45** (8:45 AM).

### Step 2: Calculate the Time from Departure to Midnight on 29th August
- From **16:30** on **29th August** to **00:00** on **30th August** is:
- 24:00 - 16:30 = 7 hours and 30 minutes.

### Step 3: Calculate the Full Day of 30th August
- The entire day of **30th August** contributes:
- 24 hours.

### Step 4: Calculate the Time from Midnight to Arrival on 31st August
- From **00:00** on **31st August** to **08:45** on **31st August** is:
- 8 hours and 45 minutes.

### Step 5: Add All the Time Intervals Together
- Now, we add the three intervals calculated:
- From 29th August: **7 hours 30 minutes**
- From 30th August: **24 hours**
- From 31st August: **8 hours 45 minutes**

### Step 6: Perform the Addition
1. Add the hours:
- 7 hours + 24 hours + 8 hours = 39 hours
2. Add the minutes:
- 30 minutes + 0 minutes + 45 minutes = 75 minutes
3. Convert 75 minutes into hours:
- 75 minutes = 1 hour and 15 minutes.
4. Combine the hours:
- 39 hours + 1 hour = 40 hours
- So, the total travel time is **40 hours and 15 minutes**.

### Final Answer
The total travel time of the journey is **40 hours and 15 minutes**.
