<h3>What is Division?</h3>
It is the inverse of the multiplication operation. It is defined as the act of forming equal groups. While dividing numbers, we break down a larger number into smaller numbers such that the multiplication of those smaller numbers will be equal to the larger number taken.
Here, Time duration of each learner = 1 minutes 30 seconds
= 3/2 minutes.
Total number of learners = 15
Time taken by all the speech category = 15 X 3/2
= 45/2
= 22 minutes 30 seconds
Thus, It will take approx. 22 minutes and 30 seconds for the speeches.
