A certain social site has grown rapidly. According to one report, about 2 million users were added each day. How many users were added, on average, each second? (Round your answer to the nearest integer.)

a) 23 users/second
b) 28 users/second
c) 31 users/second
d) 36 users/second

Answer 1

To find the average number of users added per second, divide the number of users added per day by the number of seconds in a day. The average number of users added per second is approximately 23. Therefore, the answer is a) 23 users/second.

Step-by-step explanation:

To find the average number of users added per second, we need to convert the number of users added per day to seconds. There are 24 hours in a day and 60 minutes in an hour, so there are 24 * 60 = 1440 minutes in a day. Since there are 60 seconds in a minute, there are 1440 * 60 = 86400 seconds in a day. Divide the number of users added per day (2 million) by the number of seconds in a day (86400) to find the average number of users added per second:

Average users added per second = 2,000,000 / 86,400 ≈ 23

Therefore, the answer is a) 23 users/second.
