An adult blinks 450 ti mes in 30 minutes. A 12 year old blinks about 150 times in 15 minutes. How many more times does an adult blink in 60 minutes than a 12 years old

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

An adult blinks 900 times in 30 minutes, and a 12 year-old blinks 600 times in thirty minutes. 900-600=300. Your answer is 300.
