First, let's find the number of seconds in one day:
1 day = 24 hours/day × 60 minutes/hour × 60 seconds/minute = 86,400 seconds/day
Now, we can use the information that the neon light flashes five times every 10 seconds to find how many times it will flash in one day:
In 10 seconds, the neon light flashes 5 times
In 60 seconds (1 minute), the neon light will flash 5 × 6 = 30 times
In 1 hour, the neon light will flash 30 × 60 = 1,800 times
In 24 hours (1 day), the neon light will flash 1,800 × 24 = 43,200 times
Therefore, the neon light flashes 43,200 times in one day.
