A bird files due north at velocity 20 `ms^(-1)` for 15s it rests for 5s and then files due south at velocity `24 ms^(-1)` for 10s. For the whole trip find the average speed and magnitude of average velocity

Explanation

To solve the problem, we will follow these steps:

### Step 1: Calculate Total Time
The total time for the bird's trip includes:
- Time flying north = 15 seconds
- Time resting = 5 seconds
- Time flying south = 10 seconds
