A woman drives an SUV that gets 10 mi/gal (mpg). Her husband drives a hybrid that gets 50 mpg. Every week, they travel the same
zavuch27 [327]

Answer:

The best option would be Number 1.

Step-by-step explanation:

Let's say that they each traveled 1,000 miles a week, meaning that instead of the SUV using 100 gallons of gas, it would be using 90.9, which is 9.1 gallons less.

The hybrid will only use 20 gallons of gas in that week. Meaning together, they will be 100.9 gallons a week for 1,000 miles.

In option 2, they would still be using 100 gallons of gas for the SUV a week, except, the hybrid would only be using 12.5 gallons, which is 7.5 gallons less.

The total of those together would be 112.5 gallons a week for 1,000 miles. So, it may be a small difference between the two options, yet Option 1 is the best choice on how to save gas.

netineya [11]
In order for us to easily answer this problem, let us make the units uniform. So 1 kiloliter is equivalent to 10 hectoliters. This would mean that 11 kiloliters is 110 hectoliters. Since 40 hectoliters is for making ice cream, only 70 hectoliters of milk is left to be used in other ways. Hope this answers your question. Have a great day!
