Step 1

Hi Pushpa, let's solve this interesting flight time problem together. We need to find the landing time in London by accounting for the flight duration and the time zone difference.

Flight Calculation: Chennai to London

2
Step 2

First, let's list the information given in the problem.

Given Data:

- Departure (Chennai): Sunday, 23:30 hours

- Flight Duration: 11 hours

- Time Difference: Chennai is 4.5 hours ahead of London

3
Step 3

To find the landing time in London, let's first calculate the landing time in Chennai's local time.

Step 1: Landing time in Chennai Time

$$23\!:\!30 \text{ (Sunday)} + 11 \text{ hours}$$
4
Step 4

Adding eleven hours to eleven thirty P M takes us past midnight. Adding thirty minutes gets us to midnight, leaving ten hours and thirty minutes.

5
Step 5

So, when the plane lands, it will be ten thirty in the morning on Monday in Chennai.

6
Step 6

Now, we need to convert this to London time. The problem states that Chennai is four and a half hours ahead of London.

Step 2: Convert to London Time

Since Chennai is ahead, we must subtract the time difference from Chennai time.

7
Step 7

So, London time equals Chennai time minus four hours and thirty minutes.

$$\text{London Time} = 10\!:\!30 \text{ (Monday)} - 4\!:\!30 \text{ hours}$$
