Question

The number of hours Amaal spends in his game room is proportional to the number of hours he spends playing Call of Destiny IV: Modern Battlefield. If he plays Call of Destiny IV of $6$ hours, he will spend $8$ hours in his game room. How many hours will Amaal spend in his game room if he plays Call of Destiny IV for only $3$ hours?

• A. $4$
• B. $3$
• C. $5$
• D. $8$

Answer 1

The correct option is A $4$

Now we can take the number of hours spent playing Call of Destiny as $x$ and the number of hours spent in the game room as $y$.

As they are directly proportional, we can use the equation $\frac{6}{8}=\frac{3}{y}⟹y=4$
