Question

Accepted Answer

Harish started his journey at 18:40 and finished at 22:20. To determine the time taken for the journey, we need to calculate the difference between the start and end times.

1. **Start Time:** 18:40
2. **End Time:** 22:20

To find the duration:

- From 18:40 to 19:40 is 1 hour.
- From 19:40 to 20:40 is another hour, making it 2 hours.
- From 20:40 to 21:40 is another hour, making it 3 hours.
- From 21:40 to 22:20 is 40 minutes.

Adding these together, the total time taken is 3 hours and 40 minutes.

**Explanation for Option 1:**
- Option 1 states that the journey took 3 hours and 40 minutes, which matches our calculation. Therefore, Option 1 is correct.

**Explanation for why other options are incorrect:**

- **Option 2: 3 hours 80 minutes**
  - This option is incorrect because 80 minutes is not a valid representation of time. 80 minutes would actually be 1 hour and 20 minutes, which would make the total time 4 hours and 20 minutes, not matching the calculated duration.

- **Option 3: 4 hours 40 minutes**
  - This option is incorrect because the calculated duration is only 3 hours and 40 minutes, not 4 hours and 40 minutes.

- **Option 4: 3 hours 20 minutes**
  - This option is incorrect because the calculated duration is 3 hours and 40 minutes, not 3 hours and 20 minutes.

Thus, the correct answer is Option 1: 3 hours 40 minutes.
