A girl runs along a circular track of radius 5 m starting from point A. What will be the distance travelled by her and speed
if she comes back to the initial position in 300 s

Explanation

To solve the problem step by step, we will first find the distance traveled by the girl and then calculate her speed.

### Step 1: Calculate the Circumference of the Circular Track
The distance traveled by the girl when she completes one full lap around the circular track is equal to the circumference of the circle. The formula for the circumference (C) of a circle is given by:

\[ C = 2 \pi r \]

where \( r \) is the radius of the circle.
