Acircus performer is riding a unicycle in a circle. he is riding 1.5 meters per second. he can go 15 times around the circle in 3 minutes. what is the distance around the circle? use the equation d equals=rt.

Hi, thank you for posting your question here at .

When the performer completes a full circle, he has travelled the whole perimeter of the circle. Then,

15*Perimeter = total distance
15*Perimeter= speed*time
15*P = 1.5 m/s * 3 minutes

3 minutes is equivalent to 180 s

P = (1.5*180)/15
P = 18 m = d

The answer should be c.
