Y is inversely proportional to x, and y = 500 when x = 10. What is the value of y when x = 5 and x = 15? please help

Step-by-step explanation:

the equation related to the question

y is inversely proportional to x

y=k/x

find k, when x=10, y=500

500=k/10

k=5000

y at x=5

y=5000/x

y=5000/5

y=1000

y at x=15

y=5000/x

y=5000/15

y=333.33

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
