Answer:
v = 120
Step-by-step explanation:
If v is inversely proportional to square root of d, then we can write
[tex]v \sqrt{d}[/tex] = k
If v = 30 and d = 400, then
30([tex]\sqrt{400}[/tex]) = k
k = 30(20) = 600
Now [tex]v \sqrt{d}[/tex] = 600
If d = 25, then v[tex]\sqrt{25}[/tex] = 600
5v = 600
v = 120
