Answer:the constant of proportionality is 2.5 hours per day.
The equation is y = 2.5x
Step-by-step explanation:
Let x represent the number of days that Bruno listens to podcasts.
Let y represent the total number of hours that Bruno listens to podcasts.
Bruno listens to podcasts for
two and a half hours a day.
Let k represent the constant of proportionality. Therefore,
y = kx
k = y/x
So k = 2.5/1 = 2.5 hours/day
The equation is expressed as
y = 2.5x
