what do you think it is?

or do you want me to work through it?

5 feet from the center means that your radius is equal to 5. 

r = 5 

Time is 6 seconds. 

t = 6 

First you need to find the total distance the unicorn travels in 1 rotation, which in this case is the circumference of a circle with a radius of 5.

C = 2*(pi)*r 
C = 10(pi) 

So the unicorn travels 10(pi) feet in 6 seconds. Now just have to divide. 

10(pi)/6 
In one second he travels, (5(pi))/2 feet, or about_________
