Question

If x varies inversely as y and y=60 when x=1.5. Find x when y=4. 5

Answer 1

Hi ,

x inversely proportional to y

Therefore ,

x1 y1 = x2 y2

Here ,

x1 = 1.5 ; y1 = 60

x2 = ? ; y2 = 4.5

x2 y2 = x1 y1

x2 = ( x1 y1 ) /y2

= ( 1.5 × 60 ) / ( 4.5 )

After cancellation ,

x2 = 20

I hope this helps you.
