Answer:
3.6 minutes
Explanation:
Average length of call = total time /total number of calls
between 8:00am and 11:30a.M is 3:30 mins
less break time = 3:30- 15 minutes = 3:15 minutes
It means i worked for 3: 15 minutes
For easy calculation, convert to minutes
1 hour = 60 minutes
(3 x 60) + 15 = 195 minutes
= 195/54 = 3.6 minutes
