Question

over summer vacation, emir has to read a novel for english class. he has decided to spend the same amount of time reading every day. the number of days it will take him to finish the book depends on how many hours he spends reading every day.

d = the number of days it will take emir to finish reading the book

h = the number of hours emir spends reading every day

which of the variables is independent and which is dependent?

n is the independent variable and d is the dependent variable

d is the independent variable and h is the dependent variable

Explanation:

To determine independent and dependent variables, we analyze the relationship: the number of days \( d \) to finish the book depends on the daily reading hours \( h \). An independent variable is what we choose (here, \( h \), as Emir decides daily hours), and the dependent variable is what depends on it ( \( d \), as days to finish depend on daily hours). So \( h \) is independent, \( d \) is dependent.

Answer:

A. \( h \) is the independent variable and \( d \) is the dependent variable
