An athlete complete one round of a circular track of diameter 200m in 40s. What will be the distance covered and the displacement at the end of 2minutes 20s
The athlete covers a distance equal to the circumference of the track in 40 seconds. The circumference is like going around the track once. To find the distance covered in 2 minutes 20 seconds (which is 140 seconds), we need to see how many times the athlete goes around the track in that time. Then, the displacement is just the shortest distance between the starting and ending points, which is the diameter of the track. Let's work out the distance covered and the displacement.
