#14 two cars start from the same point, at 11: 05 am, traveling in opposite directions at 45 and 24 mph, respectively. at what time will they be 460 miles apart?

21.9 hours

I think the correct answer from the choices listed above is the last option. The range of the rejected bags, x, for the bags of flour. A bag of flour is said to  weigh within 3.2 grams in order to be accepted. Therefore, it should weigh within 746.8 to 753.2 grams. Outside that range is rejected.
