Every morning you take a bus and travel 30 kilometers to school. The bus drives at the speed of 60 kilometers per hour.
The distance from the bus to your school can be modeled by
the equation s = 30 - 60h, where s is the distance traveled
in kilometers and h is the number of hours the bus have
traveled. Graph this function and see how far from your school
you will be after 0.25 hours.
