A train accelerates uniformly from rest at station A to a maximum speed of 72 km/h. The constant maximum speed is maintained for a period of time and the train then decelerates uniformly until it comes to a stop at station B. The distance between the two railway stations is 22 km and the journey takes 20 minutes. If the magnitude of the acceleration is half that of deceleration, by using the graphical method, determine the acceleration, in meters per second per second, and the time, in minutes, during which the train travels at its maximum speed.

My pug/bulldog mix, Georgia, who is blind and deaf, gets a whiff of her dinner. As soon as it registers to her that it's dinnertime, she runs 4.12 meters from the middle of our living room to our kitchen, where she is satiated with her grub. If it takes her 4.45 s to get to the kitchen, what was her speed in m/s to the nearest hundredth?
In problem 11, if the dragstrip is ¼ mile, or 402.3 meters long, at the acceleration of 24.1 m/s2, what is the time that thedragster records for his or her quarter mile run to two decimal places assuming uniform acceleration during the entirelength of the track?
