How do you differentiate between the dependent and independent variables in the first word problem?

• The dependent variable is the number of hours, and the independent variable is the number of videos.

• Both variables are independent of each other.

• Both variables are dependent on each other.

• The dependent variable is the number of videos, and the independent variable is the number of hours.

What is the equation used to convert miles to kilometers?

• Miles = Kilometers * 1.6

• Miles = Kilometers / 1.6

• Kilometers = Miles * 1.6

• Kilometers = Miles / 1.6
