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.)
