A
TIME = DISTANCE/SPEED
4
Q
What is distance measured in?
A
Metres
5
Q
What is time measured in?
A
Seconds (s - NOT ‘secs’)

Q
What is speed measured in?
A
Metres per second (m/s)
7
Q
What can speed also be measured in - other than m/s?
A
Km/ (Kilometres per hour) , if distance is in km and time is in hours.
