The average human eye blink takes 350 000 microseconds. How many times can the average person blink consecutively, at this rate, in 1 minute?

Question

 This is a math qustion 

Answer 1

The prefix "micro" means 10^-6. This means that the human eye blink takes 350,000 * 10^-6 seconds.

 

There are 60 seconds in one minute, so to find out how many consecutive blinks a human can make, we divide 350,000 *10^-6 seconds into 60 seconds.

 

60/(350,000*10^-6)=171.43. In one minute, an average human can fully blink 171 times.
