Answer:

$x = 4 \frac{6}{7}$

Step-by-step explanation:

$4(7x - 11) + 4 = 96 \\ \\ 28x - 44 + 4 = 96 \\ \\ 28x - 40 = 96 \\ \\ 28x = 96 + 40 \\ \\ 28x = 136 \\ \\ x = \frac{136}{28} \\ \\ x = \frac{34}{7} \\ \\ x = 4 \frac{6}{7}$

<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.
