Answer:
7.2 hours
Step-by-step 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
[tex]\frac{hours}{kg} =\frac{hours}{kg}[/tex]
[tex]\frac{12}{5} =\frac{x}{3}[/tex]
solve for x
cross multiply it
[tex]3 \cdot 12=5 \cdot x[/tex]
[tex]36=5x[/tex]
Divide both sides by 5
so x= 7.2 hours
