Astudent wrote four statements during math class. which statement contains an error? if iesha traveled at an average speed of 38 miles per hour for 18 hours, she traveled 684 miles. if jason traveled at an average speed of 46 miles per hour for 16 hours, he traveled 736 miles. if charmaine traveled at an average speed of 54 miles per hour for 14 hours, she traveled 766 miles. if raphael traveled at an average speed of 68 miles per hour for 12 hours, he traveled 816 miles.

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.)
