I did my best to time my own blinks and estimated it takes around 60ms to close my eyelid, which is an estimated 1cm. Therefore I could close my eye 16.7 times in a second if I didn't have to change direction to reopen. That translates to 1000 times a minute, 60,000 times an hour -- or 60,000 cm an hour.

This shocked me quite a bit. 0.6km/h seems pretty darn slow.

Since you asked the question in MPH, 0.6km = 0.372823 miles.
