Gas mileage actually varies slightly with the driving speed of a car(as well as with highway vs. citydriving). Suppose your car averages 31

31 miles per gallon on the highway if your average speed is 45

45 miles perhour, and it averages 25

25 miles per gallon on the highway if your average speed is 75

75 miles per hour.

The driving time at 45

45 miles per hour is how many hours.

The driving time is at 75

75 miles per hour is how many hours

b. Assume a gasoline price of $4.45

4.45 per gallon. What is the gasoline cost for a 2400

2400-mile trip if you drive at an average speed of 45

45 miles perhour? What is the gasoline cost at 75

75 miles perhour?

The gasoline cost at 45

45 miles per hour is how much

75 miles per hour is how much
