Speed

METRIC (DECIMAL)

Most countries use the Metric System, which uses the measuring units such as meters and grams and adds prefixes like kilo, milli and centi to count orders of magnitude.

  • Speed = 25.0 m/s
  • Speed = 2.5 * 101 m/s (scientific)
  • Speed = 25 m/s (engineering)
    • IMPERIAL

    In the USA and UK, the older Imperial system is used, where things are measured in feet, inches and pounds.

  • Speed = 90,007 m/hr
  • Speed = 82.0 ft/sec

    • Time

  • Time = 3,600 secs = 1.0 hrs
  • = 3.6 * 103 sec(s)
  • = 60 min(s)
  • = 1 hr(s)

    • Speed x Time = Distance

  • Distance = 90,007 meter
  • = 9 * 106 cm
  • = 3.54 * 106 in
  • = 295.3 * 103 ft
  • = 98.43 * 103 yard
  • = 90.01 * 103 m
  • = 90.01 km
  • = 55.93 mile
  • = 48.6 nautical mile

    • Examples

  • Car driving 24 hours at 120 km/h = 2880 km
  • 1 year x speed of light = 1 light-year
  • Garden snail on the move for 24h = 1.12 km
  • Cheetah at top speed for 30 seconds = 993 m
  • Koenigsegg CCR at 242 mph for 1 minute = 6.49 km
  • Usain Bolt at 10.44 m/s for 9.58 secs = 100 m
