The formula for speed is speed distance time. Where v is the velocity d is the distance. Therefore either speed has to be converted to kmmin or time has to be expressed in hours.
1 kmhr 518 metresecond.
Distance speed time 40156010 km. The formula for speed is s dt where s equals the speed d is the distance covered and t is the time it took to cover the distance. Speed is directly proportional to distance and inversely to time. B When Distance is constant.
