An athlete runs on a circular track of radius 49 m and covers a distance of 3080 m along its boundary. How many rounds has he taken to cover this distance?

Explanation

Radius of the circular track `(r) = 49m`

Circumference of the circular track `= 2pir = 2**22/7**49 = 308m`

So, distance covered in one round `= 308m`

Distance covered by the athlete ` = 3080m`

`:.` Total rounds taken by the athlete ` = 3080/308 = 10`
