If Sam is running on a circular track of radius 25 meters, with a speed of 5 meters per second, how long will it take him to run 1.6 laps?


A. \(6\pi\)

B. \(8\pi\)

C. \(16\pi\)

D. \(25\pi\)

E. \(80\pi\)

The circumference of the track is 50π, so 1.6 laps is 1.6 x 50π = 80π.

We’ll use the formula distance/rate = time to calculate the time it will take him to run 1.6 laps. Thus, it will take him 80π/5 = 16π seconds.

Answer: C
