1.   Four trains per day leave from Bigtown to go to Smallville. Some go nonstop while others occasionally stop to pick up and drop off passengers along the way. The A train takes 2.2 hours to make the trip. The B train takes 2 hours. The C train takes 1.8 hours and the D train takes 2.7 hours. What is the average speed of all the trains combined? The distance from Smallville to Bigtown is 122 miles. Round your answer to the nearest tenth.

2.   Brianna rode her bike around the hike and bike trail for half an hour and averaged 15 miles per hour. Morgan rode her bike around the trail and traveled 12 miles in 35 minutes. What was the difference in their average speeds? Round your answer to the nearest tenth.

3.   You have just made a lever. A first class lever (see the following figure). Your two friends like the lever so much they make copies of it. However, they are unable to exactly duplicate your measurements. Instead of 50 cm from the input force to the fulcrum, they have 47.8 and 52.6 cm on their levers. On the output side instead of 20 cm they have 20.4 and 23.4 cm. What is the average mechanical advantage of the three levers?
(Note: "mechanical advantage" or "leverage" is the ratio between how much you get out of a linkage and how much you put in.)

4.   Daniel measured the circumference of his front bicycle tire to be about 1.12 m. If the tire made 718 revolutions during a 5 minute trip, what was his average speed in m/s? Round your answer to the nearest hundredth.

5.   You and your classmates build little rubber band powered vehicles designed to pull a small box of 200 grams across the carpeted floor of your classrooms. On the final demonstration day, each car is wound up (30 revolutions) and allowed to pull the load. The distance pulled is measured. Here are the results, in order (in cm), for the 14 people that were there that day {36, 15, 33, 20, 17, 53, 30, 13, 3, 8, 28, 7, 22, 23}. Calculate (a) the mode, (b) the median, (c) the mean, and (d) the range of the distance data. Round all answers, except medium, to the nearest integer.
