Question

r is inversely proportional to s and s= 30 when r =10
Write
an equation relating r and s. find s when r = 150​

Answer 1

Answer:

s = 2

Step-by-step explanation:

Equation formed – rs = k

When two quantities are inversely proportional, their product remains constant.

=> 10 × 30 = 150 × s

=> 300 = 150 × s

=> s = 300/150

=> s = 2

Answer 2

Answer:

r.s = k

r = 10, s = 30

then k = 10×30 = 300

r.s = 300 is the equation

if r= 150 then s = 300/150 = 2
