A motorist traveled 311 miles on 12 gallons of gas. To the nearest tenth, how many miles can the motorist travel on one gallon of gas?

Answers

we know that
by using proportion
(311 miles)/(12 gallons) = (x miles)/(1 gallon) \n x= (31.1)/(12) \n x=25.9 miles

the answer is
25.9 miles
Number of miles that can be traveled on one gallon of gas=311/12
                                                                                           =25.92miles
                                                                                 =25.9miles(to the nearest tenth)

What is the difference betweeen the cost of 300g of potatoes and 300g of carrots

Answers

The cost of 300g of potatoes and 300g of carrots varies depending on the location and the time of year. However, in general, potatoes are typically cheaper than carrots.

According to the USDA National Nutrient Database, the average price for a pound of potatoes in the United States in September 2023 was $0.62, while the average price for a pound of carrots was $0.77. This means that 300g of potatoes would cost about $0.36, while 300g of carrots would cost about $0.44.

Therefore, the difference in cost between 300g of potatoes and 300g of carrots is about $0.08.

However, it is important to note that these prices are just averages and may vary depending on the specific store or market. It is also important to keep in mind that the price of both potatoes and carrots can fluctuate throughout the year.
