A wheel has a circumference of 2 meters and makes 400 revolutions, how many meters does it cover?
The distance covered by the wheel can be calculated by multiplying the circumference of the wheel by the number of revolutions it makes.
Distance covered = Circumference x Number of revolutions
In this case, the circumference of the wheel is 2 meters and it makes 400 revolutions.
Distance covered = 2 meters x 400 revolutions
Distance covered = 800 meters
Therefore, the wheel covers a distance of 800 meters.
