To solve this problem, let's break down the concept of bearings:

- A bearing is a direction measured clockwise from the north (0°). 
- The airplane flies from city A to city B at a bearing of 075°. This means the airplane is flying 75° clockwise from north.

When returning from city B to city A, the bearing would be the opposite. To calculate the return bearing, you can simply add 180° to the original bearing because the direction of travel is reversed.

Now, let’s calculate:

\[
\text{Return bearing} = 075° + 180° = 255°
\]

So, the airplane needs to fly at a bearing of **255°** to return from city B to city A.

Would you like any additional details on this? Here are a few related questions to expand on this topic:

1. What are the different types of bearings used in navigation?
2. How do bearings help in real-world navigation, such as on a map?
3. If the bearing were instead 350°, what would the return bearing be?
4. How does magnetic declination affect bearings?
5. What tools are used to measure bearings in aviation?

**Tip:** When calculating reverse bearings, always add or subtract 180°, ensuring the result stays within 0°–360°.

An aeroplane flies from city A at a bearing of 075° towards city B. What bearing does the aeroplane need to fly at to return from city B to city A?
