Question

24 cars pass through an intersection each minute while the traffic light is green. In addition, 6 cars pass through the intersection

while the light is yellow. If 84 cars pass through
the intersection during one light cycle (one green light and one yellow light), how long was the green light?

Answer 1

3.25 minutes

Explanation:

3.25 minutes per green light x 24 = 78

the yellow light is a given, hence 6 cars pass through

78 + 6 = 84 cars
