So what do we learn here? The following may or may not be factors in calculating speed and distance of an automobile traveling on the highway:

• the speed at which you can run a mile
• the relative physical conditioning of your body before running said mile
• the rate at which the car's tires spin while driving on the highway
• dividing by 2 or multiplying by 1/2 may be important at certain points in the calculations
• trucks may be slower than cars, due to greater weight of the vehicle
• automatic transmission vehicles may travel at different rates of speed than standard transmission vehicles
• improper inflation of a vehicle's tires may decrease speed
• police vehicles are probably faster than any other car

Good thing she's cute. Thank you, government schools!
