Okay so in the question it states a child swings back and forth 15 times a minute and as you know a minute is 60 seconds.

So basically we just have to divide 15 by 60 to find the frequency 

15 ÷ 60 = 0.25

So your answer would be 0.25 Hertz (The second option)

Hope this helped. Have a great night!
