0.0666667%
total time for ad= (8*60)+(16*30)=480+480=960 secs=16 min
total duration of programme = 4 hrs = 240 min
% of ad= 16/240= 0.0666667

Answer 2

Answer:

The percentage of time devoted in a day for the advertisement is Explanation:

Percentage: the number, amount, rate, etc. of something, expressed as if it is part of a total which is a hundred; a part or share of a whole

According to the question

$8 am$ to $12am=4hrs=240 minutes$

$60 \times 8=480sec=\frac{480}{60}=8 min$

$\frac{16 \times 30}{60}=8 min$

Total advertisement $16 min$ out of $240 min.$

i.e., $\frac{16}{240} \times 100=\frac{20}{3}=6.7$%.

Hence, the percentage of time devoted in a day for the advertisement is $6.7$%
