Question description

The SI unit of distance is meter and the SI unit of time is second, both of which are base units. The SI unit of speed is meters per second and speed is a derived unit and so it is represented in the SI units of the base units, distance and time. Meter can be defined as the distance which is traveled by light in a vacuum in 1 /29,792,458th of a second, and second is defined as the amount of time of 9,192,631,770 periods of the radiation which corresponds to the transition between the hyperfine levels of the ground state of cesium 133 atom.
