Step 1: Start Time Calculation
The car starts at 9:40 AM.
Step 2: Adding the Travel Time
The car takes 4 hours and 50 minutes to reach city Q.
So, we need to add this travel time to the starting time of 9:40 AM.
We break the time into two parts:
Add 4 hours to 9:40 AM:
\[
9:40 \, \text{AM} + 4 \, \text{hours} = 13:40 \, \text{(or 1:40 PM)}
\]
Add the remaining 50 minutes:
\[
13:40 \, \text{(1:40 PM)} + 50 \, \text{minutes} = 14:30 \, \text{(or 2:30 PM)}
\]
So, the correct arrival time is: 14:30 Hours.
