z * t = k ... 16 * 12 = 192
z * 4 = 192
Suppose z varies inversely with t and that z=16 when t=12. What is the value of z when t=4 ?

Your 3 posts are all the same, I will do this one
"z varies inversely with t" ----> z = k(1/t) or z = k/t
given: z=16 when t=12
16 = k/12
k = 12(16) = 192
So z = 192/t
when t = 4
z = 192/4 = 48
"z varies inversely with t" ----> z = k(1/t) or z = k/t

k = 12(16) = 192
So z = 192/t
when t = 4
z = 192/4 = 48
