Through a lot of material that includes these basic patterns, and you have compared
grammatically correct and incorrect sentences, write down what you think is a rule that could explain what makes a sentence
grammatically correct or not. For example, you might write something like: "verbs always match nouns in number, and they
usually come before the noun." In other words, make your best guess for the grammar rule that makes sense out of the
pattern(s) you see in the phrases you have been working with. Review if you need to, and you might briefly check your
hunches against the sentences you have been working with in this or previous modules. Keep in mind that what you're after
is your hunch, not a grammar rule from a text book. Now check your hunch with the explanation of this principle in the
following pattern.

Gas mileage actually varies slightly with the driving speed of a car (as well as with highway vs. city driving). suppose your car averages 33 miles per gallon on the highway if your average speed is 54 miles per hour, and it averages 22 miles per gallon on the highway if your average speed is 75 miles per hour. answer parts (a) and (b) below. a. what is the driving time for a 2000-mile trip if you drive at an average speed of 54 miles per hour? what is the driving time at 75 miles per hour? the driving time at 54 miles per hour is nothing hours. (type an integer or decimal rounded to two decimal places as needed.) the driving time is at 75 miles per hour is nothing hours. (round to two decimal places as needed.) b. assume a gasoline price of $3.33 per gallon. what is the gasoline cost for a 2000-mile trip if you drive at an average speed of 54 miles per hour? what is the gasoline cost at 75 miles per hour? the gasoline cost at 54 miles per hour is $ nothing. (round to two decimal places as needed.) the gasoline cost at 75 miles per hour is $ nothing. (round to two decimal places as needed.)
