If G is the number of seconds that a traffic light says green and n is the average number of cars in each lane per light cycle,
then the relationship would be G= 2.1n + 3.7 if the light stays green for 70 seconds then how many cars can cross the intersection in one cycle?
(linear equations)
31.57 cars is the answer rounded to the hundredth, but since its cars you might want to put just 31 since half a car cant pass through. it depends on what your teacher wants really.
