Question

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

Answer 1

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.
