Answer:
9
Explanation:
Given that :
Number of intersection driven through = 36
At 4 of every 16 intersections, there is a red light;
Hence, the rate of red light per intetaection could be calculated as ;
Number of red lights / number of intersections
4 / 16 = 1 /4
Hence, driving through 36 intersections,
Number of red lights will be ;
(1 /4) * 36
= 9 red lights = 9 stops
