A)Her speed is 4.4 m/s, and her velocity is 0 m/s.

Step-by-step explanation:

The formula to calculate the speed is given by :-

$\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}$

Given: The length of the track = 400 meters

Time taken to complete 4 laps = 6 minutes =

The total distance covered in 4 laps = $4\times400=1600\text{ meters}$

Now, her speed is given by :-

$\text{Speed}=\dfrac{1600}{6\times60}}\approx4.44\text{ m/s}$

Since the starting point and the ending point is same , then the her displacement is zero.

Hence, velocity =0
