  • The units for speed will depend on the units for distance and time.
  • If distance is measured in metres (m) and time is measured in seconds (s), the units for speed will be metres per second (m/s).
  • If distance is measured in kilometres (km) and time is measured in hours (hr), the units for speed will be kilometres per hour (km/hr).
