1.  On planet X, the atmospheric pressure is lower than it is on planet Y. Interplanetary probes were recently sent to the two planets and data were obtained on many things including the atmospheric pressure. The pressure on planet Y is16N/m^{2}. If the pressure on planet X istwothirdsthat of planet Y, what is the pressure, in Pascals, on planet X? Round your answer to the nearest hundredth if necessary.

 2.  Makayla is trying a new fuel formula in her gokart. In her first trial, fuel mixture A resulted in a maximum speed of24miles per hour on a flat smooth road. On the same road, mixture B resulted in a maximum speed of60miles per hour. Mixture B appears to increase the maximum speed of the gokart by what factor? Express your answer as a ratio of speeds.


3.  Space ship Z is traveling at178,000miles per second. Spaceship Q is traveling at171,000miles per second. What is the ratio of speeds (Z/Q) of the two spaceships? Express your answer in terms of the maximum speed of light, which is186,000miles per second.

 4.  A sealed steel container of methane gas is slowly heated. The temperature increases by5C every15minutes. If the initial temperature was30C, what will the initial to final temperature ratio (T_{i}/T_{f}) be after two hours?


5.  Jacob calculated the mass of a toy car to be27.2grams. Jason calculated the mass of the same car but made an error and obtained a mass that was greater than Jacob's by a ratio of5to3. What was Jason's calculation for the mass of the car?
