A 12 year old blinks about 150 times in 15 minutes. How many times does a 12 year old bink in 1 day?
shepuryov [24]

Answer:

14400 blinks per day

Step-by-step explanation:

We need to convert minutes to days

60 minutes = 1 hour

24 hours  = 1 day

The units will cancel leaving blinks per day.

150 blinks       60 minutes           24 hour       216000

---------------- * ----------------------  * ------------   =   ---------------  blinks/day

15 minutes        1 hour                     1 day            15

14400 blinks per day
