Answer: 16.33 feet/s Explanation: 1) Data: 2) Formulae: ω = number of rpm × 2π / 60 seconds  v = ω × r 3) Solution: 
                                
             
                    
              
Answer: There is linear velocity of 75 feet per hour of the children. 
Step-by-step explanation: 
Since we have given that 
Time taken by merry - go - around = 12 times per minute
Distance from the center of the wheel when they are in their seats = 15 feet
We need to find the linear velocity of the children in feet per hour.
According to question,  
Linear velocity = 
So, it becomes,
Linear velocity is given by 
Hence, there is linear velocity of 75 feet per hour of the children.
