milly reads 20 pages in 4 minutes sara reads 12 pages in 3 minutes find each constant of proportionality and write a direct variation eqyation then

Answer 1

To find the constant of proportionality, we can divide the number of pages by the number of minutes for each person.

For Milly: 20 pages / 4 minutes = 5 pages/minute
For Sara: 12 pages / 3 minutes = 4 pages/minute

Therefore, the constant of proportionality for Milly is 5 and for Sara is 4.

The direct variation equation is y = kx, where y represents the number of pages and x represents the number of minutes.

For Milly, the equation is y = 5x.
For Sara, the equation is y = 4x.
