AN ADULT BLINKS ABOUT 450 TIMES IN 30 MIN. 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? (PLEASE EXPLAIN CLEARLY)
so an adult would blink 15 times per minute and a 12 yr old 300 in 30 minutes.. so 10 times per minute.. so an adult 900 times in 60 mins.. and a 12 yr old 600 times in 60 mins.. so an adult blinks 300 more times than a 12 yr old
