Answer 2

P = 5

Explanation:

given that P is inversely proportional to w then the equation relating them is

P =
`(k)/(w)` ← k is the constant of variation

To find k use the condition P =
`(10)/(13)` when w =
`(1)/(8)`

k = Pw =
`(10)/(13)` ×
`(1)/(8)` =
`(10)/(104)` =
`(5)/(52)`

Hence

P =
`(5)/(52w)` ← equation of variation

When w =
`(1)/(52)` then

P =
`(5)/(52(1/52))` =
`(5)/(1)` = 5
