Explanation / Answer

Vair = 331.3 + 0.606 * 20 = 343.42 m/s

L = 2.58 m

f = V/ 2L =  343.42 / ( 2 * 2.58 ) =66.5542636

f = 20 , 000 Hz uppper limit of audibal frequncy

20 , 000 = n * 66.5542636

n = 20000/ 66.5542636 =300.506668 answer for A

n = 300

closed f = V/ 4L = 66.5542636 / 2 = 33.2771318

n = 20000 /33.2771318 =601.013336  

n = 601 answer for B
