A train engineer started the train from a standstill and sped up to 5 meters per second, she then rounded a corner at a constant speed. She then sped the train up to 10 meters per second on the next straightaway. Next, the train chugged around another bend at 10 m/sec, and then its speed slowed to 5 meters per second after coming out of the bend. Finally, the train reached the station, and the engineer applied the brakes and brought the engine to a stop. How many times did the train accelerate?

Mr. Garcia's science class did an experiment to see who could walk the greatest distance in a certain amount of time. Mr. Garcia told his students he would measure how far they walked during the school day, from 9:00 AM until 3:00 PM. That is, all the students walked for 6 hours. The next day, the class graphed the data. Here is a comparison of the boys and girls: how far they walked in 6 hours. Which group walked the fastest?

C) 6 mile group
D) 7 mile group
