2Sample OneScience fiction often uses nautical analogies to describe space travel. If the starship U.S.S. Enterprise is traveling at warp factor 1.71, what is its speed in knots and in miles per hour? (Warp = 5.00 times the speed of light; speed of light = 3.0x108 m/s; 1 knot=2000 yards/hour, exactly.)
3Sample TwoThe world record for the hundred meter dash is sec. What is the corresponding average speed in units of m/s, km/hr, ft/s, and mi/hr? At this speed, how long would it take to run 1.00x102 yards?
4Sample ThreeWould a car traveling at a constant speed of 65 km/hr violate a 40 mi/hr speed limit?
5Sample FourYou pass a road sign saying “New York 112 km.” If you drive at a constant speed of 65 mi/hr, how long should it take you to reach New York? If your car gets 28 miles to the gallon of gasoline, how many liters are necessary to travel 112 km?
6Sample FiveIf you put 8.21 gallons of gas in your car and it costs you a total of $17.25, what is the cost of gas per liter in Canadian dollars? Assume 0.82 dollar US = 1.00 dollar Canadian
7Sample SixA children’s pain relief elixir contains 80 mg acetaminophen per 0.50 teaspoon. The dosage recommended for a child who weighs between 24 and 35 lb is 1.5 teaspoons. What is the range of acetaminophen dosages, expressed in mg acetaminophen/kg body weight for children who weigh between 24 and 35 lb?
