To find the average number of calls per second, we need to convert the rate from calls per 2 minutes to calls per second.

Step 1: Convert the rate to calls per minute:

The rate is given as 5 calls every 2 minutes. So, the rate is 5/2 calls per minute.

Step 2: Convert the rate to calls per second:

Since there are 60 seconds in a minute, the rate is (5/2) / 60 calls per second.

Step 3: Simplify the expression:

(5/2) / 60 = 5 / (2 * 60) = 5 / 120 = 1/24

Answer: The average number of calls per second is 1/24. Therefore, the correct option is e) 1/24.

Step 1: Convert the rate to calls per minute:

The rate is given as 5 calls every 2 minutes. So, the rate is 5/2 calls per minute.

Step 2: Convert the rate to calls per second:

Since there are 60 seconds in a minute, the rate is (5/2) / 60 calls per second.

Step 3: Simplify the expression:

(5/2) / 60 = 5 / (2 * 60) = 5 / 120 = 1/24

Answer: The average number of calls per second is 1/24. Therefore, the correct option is e) 1/24.
