<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.
