Answer:

7.2 hours

Explanation:

Myra is cooking meat the double number line shows that he needs 12 hours too cook 5 kilograms of meat

12 hours to cook 5 kilograms of meet

we need to find the number of hours needs to cook 3 kilograms

Let x be the number of hours to cook 3 kilograms

Make a proportion


(hours)/(kg) =(hours)/(kg)


(12)/(5) =(x)/(3)

solve for x

cross multiply it


3 \cdot 12=5 \cdot x


36=5x

Divide both sides by 5

so x= 7.2 hours
