how far does the first car will drive in the 2 hours head start it gets? now, at t = 2 hours, both cars are moving. how much faster is the second car than the first car? you can determine this by dividing the head start by the difference in the two speeds. if car 1 has a 20-mile head start, and car two is five mph faster, then it will take 20/5 = 4 hours to catch up.

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
