An adult blinks about 450 times 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-year-old?

150x2 because 15 minutes is half that of 30 =300 then times that by 2 again to get an hour so 600 then times 450 by 2 to get an hour so 900 then subtract 600 from 900 which is 300 300 more times is your answer
