An electronic advertising sign repeats a message every 7 seconds, day and night, for a week. How many times did the message appear on the sign?
Step 1 of 1:
Consider an electronic advertising board repeats a message every 7s. We are going to find the number of times the message appear on for a week.
Time t = 7s
The number of seconds in a week n = 7 x 24 x 60 x 60 s
The number of blinkings
N = 86,400
The message repeats 86,400 times in a week.
