a stoplight flashes red for 50 seconds, yellow for 5 seconds, and green for 65 seconds. For what fraction of a 24-hour day is the stoplight yellow?
5/120 = 1/24
how do u get that
i don't understand please exlpain
actally 2 dif ppl we in same class and i showed her the website and she typed q after i did. thank u
You're welcome.
First, Cat/Henry -- please don't switch user names -- especially for the same question.
50 + 5 + 65 = 120
Five seconds is 1/24 of 120.
To find the fraction of a 24-hour day the stoplight is yellow, we need to divide the total time the stoplight is yellow by the total time in a 24-hour day.
Step 1: Convert 24 hours to minutes.
Multiply 24 hours by 60 minutes per hour:
24 hours * 60 minutes/hour = 1440 minutes
Step 2: Determine the total time the stoplight is yellow.
The stoplight is yellow for 5 seconds. There are 60 seconds in a minute, so we convert the time to minutes:
5 seconds / 60 seconds per minute = 0.0833 minutes
Step 3: Calculate the fraction of a 24-hour day the stoplight is yellow.
Divide the total time the stoplight is yellow by the total time in a 24-hour day:
0.0833 minutes / 1440 minutes = 0.0000576
Therefore, the stoplight is yellow for approximately 0.0000576, or about 0.00576% of a 24-hour day.
