Answer:
5 9/11
Step-by-step explanation:
I think you have to divide by 10
If 85 blinks = 15 minutes
then 51 blinks = x (cross multiply)
85 × x = 51 × 15
85x / 85 = (51 x 15) / 85
x = (51 × 3) / 17
x = 3 × 3
x = 9
so he blinked 51 times in 9 minutes
if 1 minute = 60 seconds
then 9 minutes = x (cross multiple)
1 × x = 9 × 60
x = 540
therefore 540 seconds passed when he blinked 51 times
