If a girl runs around a circular track of length 400 m and comes back to the initial point in 40 s, what would be her speed and velocity?

Text Solution

AI Generated Solution

To solve the problem, we need to find both the speed and the velocity of the girl running around the circular track. ### Step-by-Step Solution: **Step 1: Calculate Speed** - **Definition of Speed**: Speed is defined as the total distance traveled divided by the total time taken. - **Total Distance**: The girl runs around a circular track of length 400 meters. Therefore, the total distance traveled is 400 meters. - **Total Time**: The time taken to complete the track is 40 seconds. ...
