Problema Solution
Brandon is riding his bicycle at a constant speed from to the library. His distance from the library in kilometers x hours after leaving school can be modeled by the equation y=20 - 12x. What do x, y, and 12 each represent in the equation? Be sure to specify units.
Answer provided by our tutors
y = 20 - 12x
y is the distance from the library in kilometers x hours after leaving school.
20 is the initial distance in kilometers at time zero (x = 0).
12 is the average speed of Brandon in kilometers per hour.
x is the time in hours after leaving school.
