If your speedometer broke, how could
you measure your speed?
On a highway, check out the little mileage
signs along the side.
In many states, there are distance
markers every mile, and sometimes blank markers every tenth
of a mile.
If you have a stopwatch or a watch with a second
hand, you can calculate your speed using this formula:
Miles Traveled in a minute x 60
minutes = Miles Per Hour
