Kilometre km and metre m is usually taken as the unit of distance. To find distance speed is beside time so distance is speed multiplied by time. 1 metresecond 185 kmhr.
It describes distance travelled divided by the time taken to cover the distance.
While solving the questions you might get confused on the right formula and tricks to apply to get the answer. The triangles will help you remember these three rules. Therefore either speed has to be converted to kmmin or time has to be expressed in hours. We know the formula for Speed DistanceTime Speed 400 km5 hr 80 kmhr The speed at which a car travels is 80 kmhr.
