    An adult blinks 450 times in 30 minutes ... so they blink 450 * 2 = 900 times in 60 minutes.

    a 12 yr old blinks 150 times in 15 minutes ... so the kid blinks 150 * 4 = 600 times in 60 minutes.

    The adult blinks 300 more times then the kid does (in 60 minutes)

    90 because how many more means to subtract so u subtract 150 from 60 and you will get 60.
