Answer:

see explanation

Explanation:

The statements tells us that w is inversely proportional to v and the equation relating them is

v =
(k)/(w) ← k is the constant of proportion

To find k use the condition v = 9, w = 5, that is

9 =
(k)/(5) ( multiply both sides by 5 )

45 = k

v =
(45)/(w) ← equation of proportion

When w = 4 , then

v =
(45)/(4) = 11.25
