Question

the proportional relationship between the total number of minutes, m, that bo practices the piano after some number of days, d, can be represented by the equation m = 60d. at what rate did he practice, in minutes per day?

Explanation:

Step1: Recall the formula for proportional relationships

In a proportional relationship of the form \( m = kd \), where \( m \) is the total quantity, \( d \) is the number of units (in this case, days), and \( k \) is the constant of proportionality (which represents the rate).

Step2: Identify the rate from the given equation

The given equation is \( m = 60d \). Comparing this with the general form \( m = kd \), we can see that \( k = 60 \). This \( k \) is the rate at which Bo practices the piano, in minutes per day.

Answer:

60
