Question

At ${350}^{\circ }F$, an oven can cook approximately 3 pounds of pork per hour. At ${450}^{\circ }F$, it can cook approximately $4.5$ pounds per hour. Calculate the difference in ounces of pork can the oven cook at ${450}^{\circ }$ than at ${350}^{\circ }$ in $10$ minutes.
(Note : $1$ pound $=16$ ounces)

• A. 4
• B. 6
• C. 8
• D. 12

Answer 1

The correct option is A 4

Given oven can cook approximately $3$ ponds of pork par hour at ${350}^0$

And oven can cook approximately $4.5$ ponds of pork par hour at ${450}^0$

Then, oven can cook approximately of pork in $10$ minutes at ${350}^0$ $=$ oven can cook approximately of pork in $10$ minutes at ${350}^0$ $=$ $\frac{3}{60}\times 10=\frac{1}{10}$=0.50 ponds=8 ounces

And thenoven can cook approximately of pork in $10$ minutes at ${450}^0$=$\frac{4.5}{60}\times 10=\frac{1.5}{2}=0.75$ ponds=12 ouncs

Then difference of 450 and 350=12-8=4 ounces
