A student is in class 400 minutes every day for 5 days each week. How many seconds is this?
Conversion factors: 1 day = 24 hours; 1 hour = 60 minutes; 1 minute = 60 seconds
120,000 sec
12,000 sec
60,000 sec
1,200,000 sec
To convert 400 minutes to seconds, we need to multiply it by the conversion factor of 1 minute = 60 seconds.
400 minutes * 60 seconds/minute = 24,000 seconds
Since the student is in class for 5 days each week, we need to multiply the seconds by 5.
24,000 seconds * 5 days = 120,000 seconds
Therefore, the student is in class for 120,000 seconds each week.
To calculate the number of seconds a student is in class in 5 days, we need to convert the minutes to seconds.
Starting with 400 minutes:
400 minutes * 60 seconds/minute = 24,000 seconds
Since the student is in class for 5 days each week, we multiply by 5:
24,000 seconds/day * 5 days/week = 120,000 seconds/week
Therefore, the correct answer is 120,000 seconds.
