Question

Sam counted 14 blinks in 34 seconds. How many times does Sam blink in a day if we assume he sleeps for eight hours.

Answer 1

14 blinks in 34 seconds needs to be converted to so many blinks per day.

$\dfrac{14 \text{ blinks}}{34 \text{ seconds}} \cdot \dfrac{60 \text{ seconds}}{1 \text{ minute}} \cdot \dfrac{60 \text{ minutes}}{1 \text{ hour}} \cdot \dfrac{16 \text{ hours awake}}{1 \text{ day}} = \dfrac{14 \cdot 60 \cdot 60 \cdot 16 \text{ blinks} }{1 \text{ day}}$

806,400 blinks/day (assuming he sleeps 8 hours per day)
