Randy can run \(\pi\) meters every 2 seconds. If the circular track has a radius of 75 meters, how many minutes does it take Randy to run twice around the track?

A. 150 seconds

B. 300 seconds

C. 600 seconds

D. 1200 seconds

E. 22500 seconds

Kudos for a correct solution.

Bunuel, the question asks about minutes while the options are in seconds. Please correct one of them.

\(\pi\) m in 2 seconds are run by Randy. Distance to be covered to run twice around the track : \(2*2*\pi*r\), as circumference of a circle = 2*\pi*r

Given, r=75 m,

Thus total distance to be covered = \(300\pi\)

Speed = \(\pi/2 ms^{-1}\)

Thus, time = distance/speed = \(300\pi\)/\(\pi/2 ms^{-1}\) = 600 seconds = 10 minutes , C is the correct answer
