3 / 10
Answer:
see explanation
Step-by-step explanation:
The statements tells us that w is inversely proportional to v and the equation relating them is
v =
← k is the constant of proportion
To find k use the condition v = 9, w = 5, that is
9 =
( multiply both sides by 5 )
45 = k
v =
← equation of proportion
When w = 4 , then
v =
= 11.25
