Answer:
300 more times
Step-by-step explanation:
It is mentioned that a 12 years old blinks 150 times in 15 mins.
We know that 15 times 4 is 60 which results in 600 times in 60 minutes.
Again, an adult blinks 450 times in 30 minutes.
We know that 450 times 2 is 900
Next, subtract 600 from 900
equals to 300 times more
