The following chart shows the number of telephone conversations at a Call Centre for various call durations on a particular day.
How many minutes of telephone conversations took place on that day?
To find the total minutes of telephone conversations that took place at the Call Centre on that particular day, we need to analyze the information given in the chart.
The chart shows the number of telephone conversations for various durations. The data can be broken down as follows:
| Duration (minutes) | Number of Calls |
|---|---|
| 1 minute | 4 |
| 2 minutes | 14 |
| 3 minutes | 40 |
| 4 minutes | 30 |
| 5 minutes | 12 |
To calculate the total minutes of conversations, we multiply the duration of each call by the number of calls for that duration and sum up all these products:
Adding all these together gives us the total minutes:
\(4 + 28 + 120 + 120 + 60 = 332\)
Thus, the total number of minutes of telephone conversations that took place on that day is 332.
Therefore, the correct answer is: 332.
