1 metresecond 185 kmhr. Velocity calculations are easy to do - you just need to know a few tricks to get your answers exact. If any of the two values among speed distance and time are given we can use this formula and find the unknown quantity.
Speed is measured as distance moved over time.
Its average speed is 50 km per hour 50 kmh. So 1 km hour 5 18 m sec To convert from m sec to km hour we multiply by 18 5. Speed is directly proportional to distance and inversely to time. Distance rate x time When identifying the parts of the word problem distance is typically given in units of miles meters kilometers or inches.
