WebSecondary Math Solutions. This is a set of notes and practice on setting up and solving Real-life Rational Functions situations. The notes include 3 examples to teach the concept: one "job problem" and two "distance" problems. The student uses a template to help set up the equation for the distance problems. WebWhen solving these problems, use the relationship rate (speed or velocity) times time equals distance. r⋅t = d r ⋅ t = d For example, suppose a person were to travel 30 km/h for 4 h. To find the total distance, multiply rate times time or (30km/h) (4h) = 120 km. The problems to be solved here will have a few more steps than described above. fitzrovia riding house
