A bus leaves at 12.25 noon and reaches destination at 10.45 am . The duration of the journey is ________

Correct option is A

Given:

• Departure time: 12:25 noon
• Arrival time: 10:45 AM (next day)

We need to calculate the duration of the journey.

Step 1: Break the Time into Two Parts

1. Time from 12:25 PM (noon) to midnight:
   There are $12$ hours from noon to midnight. Subtract 25 minutes:

   $$12:00-12:25=11\text{hours and }35\text{minutes}.$$

2. Time from midnight to 10:45 AM:
   This is straightforward:

   $$10\text{hours and }45\text{minutes}.$$

Step 2: Add the Two Time Periods

• $11\text{hours and }35\text{minutes}$
• $10\text{hours and }45\text{minutes}$

Add the hours and minutes:

1. Hours: $11+10=21$
2. Minutes: $35+45=80$

Since $80\text{minutes}=1\text{hour and}20\text{minutes}$, we add 1 hour to the total hours:

$$21+1=22\text{hours}$$

Thus, the total duration is:

$$22\text{hours and }20\text{minutes}.$$

Final Answer:

The duration of the journey is 22 hours and 20 minutes.
