The graph below represents the speeds of Kael and Lynn as they run around a track. A graph titled The Running Track. The horizontal axis shows time (minutes) and the vertical axis shows speed (m p h). Two lines begin at 0 speed in 0 minutes. The line labeled Lynn goes to 3 m p h in 8 minutes, to 12 m p h from 13 to 28 minutes, to 0 m p h in 40 minutes. The line labeled Kael goes to 10 m p h from 12 to 20 minutes, to 2 m p h in 32 minutes, to 0 m p h in 40 minutes.

For how many minutes did Lynn run at a greater speed than Kael?

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.)
