categorical variables in the survey that was conducted are family size, dad's
occupation, whether mom works, and kind of pets. Remember that the categorical
variable is also known as a qualitative variable. It means that categorical
variables are mostly descriptions of something, can be an individual or group

180 = 20x
x = 9
Distant = 80 * 9 = 720 miles
