Question

myron is cooking meat. the double number line shows that he needs 12 hours to cook 5 kilograms of meat.

meat (kg) 0 5
time (hours) 0 12

based on the ratio shown in the double number line, how long does myron need to cook 3 kilograms of meat?

hours

Explanation:

Step1: Find the rate per kg

To find how long it takes to cook 1 kg of meat, we divide the total time by the total mass of meat. So, the time per kg is $\frac{12}{5}$ hours per kg.

Step2: Calculate time for 3 kg

Now, to find the time for 3 kg, we multiply the rate per kg by 3. So, $3\times\frac{12}{5}=\frac{36}{5} = 7.2$ hours.

Answer:

7.2
