The constant of proportionality is 4 .
The equation is [ Height = (4) times (Days) ] .
When the sunflower is 60cm tall, 60 = (4) times (Days).
Divide each side of the equation by 4: 15 = Days
itwould be the 25 day the sunflower would be 60 cm tall
The constant of proportionality relates height and days for the sunflower's growth. Using the equation Height = 4 × Days , we find it takes 15 days for the sunflower to reach 60 cm. This is calculated by solving 60 = 4 × Days .
