1.  Robert is hiking in the national park. He is on a6 1/4-mile hike and he makes four evenly spaced rest stops along the way. At what mile of the hike does he make his last stop?

2.  Mr. Bloop is giving a demonstration using two hard rubber balls. He is dropping them from his hands to the floor and measuring the width of the dents they make in a piece of polystyrene foam. The one that has the most kinetic energy when it hits leaves the widest dent. Both balls have a radius of2 1/2cm but their masses are different. The red ball is11 2/3Gramm und das Blau darauf ist16 1/2grams. If the blue one is held2 2/3m von der Oberfläche des Schaums und der rote wird gehalten2 1/2m up, which one should make the larger dent? You do not need to know the value for the acceleration of gravity to solve this problem!

3.  Jasmine estimates thattwo-fifthseiner bestimmten Steinart eine Masse hat, größer alsone-eighthof a gram. If she has540of these stones, about how many stones have a mass less than or equal toone-eighthof a gram?

4.  A bus is making a trip from Bigtown to Megacity. The average round trip speed is always59MPH on this journey. The round trip distance is120miles. At Megacity the bus waits exactly24minutes and then returns to Bigtown. If the bus has completed5/6of this entire journey, how long has it been since it left Bigtown on the way to Megacity? Round your answer to the nearest minute.

5.  Jordan is riding her bicycle on the hike and bike trail around Village Lake. She rides25minutes and travels9 1/3miles. She then takes a10minutes rest. After resting (and eating an energy bar) she rides another35minutes and covers12 1/2miles. What was her average speed for the entire trip in miles per hour? (include the time she rested in the answer)

6.  Zwei Gegenstände (sehr kleine Raumschiffe nämlich) trafen auf eine Wand auf. Gegenstand eins traf mit einer Kraft von7/13eines Newtons auf der Wand auf und Gegenstand zwei traf mit einer Kraft von4/7eines Newtons auf. Beweise welches die größere Kraft aufgewendet hat. (Kraft = Masse x Beschleunigung)
