George found that he blinked 85 times in 15 minutes. at this rate, how many seconds passed during 51 blinks?

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.

About 561 seconds passed in 51 blinks.
