How Fast?Science brain teasers require understanding of the physical or biological world and the laws that govern it.
When you are driving a car down the street at a hundred miles an hour, in reality you are moving much faster.
AnswerThe earth is flying through space fairly fast, so you are moving at different speeds, greater than a hundred miles an hour.
The hundred miles an hour on the car may add to or subtract from your total speed. You are only moving 100 miles an hour in relation to the road. In space, your motion is much faster and much more complicated.
