To solve this first we have to find out how many seconds are in 15 minutes. So, 15 x 60 since there is 60 seconds in a minute, and of course there are 15 minutes. 15 x 60 = 900 seconds. Now we need to find out about how many seconds does it take George to blink once. So we divide 900 seconds by 85 blinks. 900 / 85 = About 11 seconds for one blink. Now we use the rate of 1 blink = 11 seconds and multiply. Since they said 51 blinks you would multiply 51 blinks by 11 seconds. 51 x 11 = About 561 seconds. Answer: About 561 seconds passed in 51 blinks.
