Answer:
effective green time = 35 seconds
Step-by-step explanation:
given data
cycle length = 60 seconds
effective red time = 25 seconds
solution
we get here effective green time that is express as
effective green time = cycle length - effective red time ...........................1
put here value and we will get
effective green time = 60 seconds - 25 seconds
effective green time = 35 seconds
