The first step we need is tounderstand the given and then make an equation, so that we can solve the given problem.After that, let us solve for the value of K. The solution must be like this:4=k/300 ~ Cross multiply, put imaginary one under the number 4 to make it a fraction, like this:4/1=k/300Then do the cross multiply(K)(1)=K(4)(300) = 1200 K=1200The value of K is 1200.
Next, after solving for the value of K, we need to find how long will it takes for us to read a novel with 150 pages. Let's use this equation: t=k/p to find what the problem is asking!t=1200/150=8Therefore, it will take us 8 hours for us to read a novel with 150 pages

I'm glad we worked through this together! Let's now start reading the novel!
WOAH! great job, Mark! now we know how to manage our reading time based on the number of pages.Inverse Variation, Our Secret Superpower!

Yeah, you're right! I'm glad you still remember it. Do you want to read some books? like the novel one?
I think I remember that you love reading books?
NOVEL
Sure, I'd love to! but wait, we need to find a time for us to be able to finish a novel within the day!

Hmmm.. alright! let's find time tofinish the book. Good thing that I stillremember our lesson in Mathematics before, the Inverse Variation. Byapplying the Inverse Variation in our problem, we can know how long will it take to read a novel within the day.

Let's solve this given sample problem! Just listen to me.

Given: Josh and Mark has found out that the time required to finish a book is inversely proportional to the number of pages in the book. If Josh and Mark takes 4 hours to read a novel with 300 pages, how long will it take them to read a novel with 150 pages?
