Respuesta :
Its C because it equals 120 minutes which is 20 times 6 and you have to add because 12 ounces is .75 lbs and 75% of 20 minutes is 15 and you add 15 minutes to the time which it will be 6:35
By converting ounce to pound, If the roast was placed in the oven at 4:20 pm, it should be done by 6:35 pm.
How to convert ounces to pound?
1 ounce (oz) is equal to 0.0625 pounds (lbs.).
6 lbs. 12 oz. = 6 lbs. + 12(0.0625) lbs. = 6.75 lbs.
Time taken to roast 1 pound = 20 minutes
Time taken to roast 6.75 pounds = 6.75 * 20 = 135 minutes = 2 hours 15 minutes
If the roast was placed in the oven at 4:20 pm, it should be done by 4:20 pm + 2 hours 15 minutes = 6:35 pm.
