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
12,000 sec
1,200,000 sec
120,000 sec
60,000sec
To find the number of seconds that the student is in class, you can multiply the number of minutes by the conversion factors:
400 minutes/day * 5 days/week = 2000 minutes/week
2000 minutes/week * 60 seconds/minute = 120,000 seconds/week
Therefore, the student is in class for 120,000 seconds. Therefore, the correct answer is 120,000 sec.
To find the number of seconds a student is in class, you can multiply the number of minutes by the number of seconds in each minute. Let's calculate the total number of seconds:
Number of minutes in a day = 24 hours × 60 minutes = 1440 minutes
Number of minutes in a week = 1440 minutes × 5 days = 7200 minutes
Number of seconds in 7200 minutes = 7200 minutes × 60 seconds = 432,000 seconds
Therefore, a student is in class for 432,000 seconds.
