Speed,Time and Distance

The basic formula says Speed= Distance/Time . From this formula, it is evident that speed is directly proportional to distance and inversely proportional to time.

Important Concept

If Time taken as Constant:- Distance travelled directly proportional to speed i.e. More speed, more distance.

If Time is constant : Distance is directly proportional to speed.

Example-:
D₁/D₂=S₁/S₂

If Speed taken as Constant:- Distance travelled directly proportional to time i.e. More distance, more time.

If Speed is constant : Distance is directly proportional to Time.

Example: D₁/D₂=T₁/T₂

If Distance taken as Constant:- Speed is inversly proportional to time i.e. More speed,less the time .

If Distance is constant : Speed is inversly proportional to Time.

Example: S₁/S₂=T₂/T₁

Conver km/h to m/s.
1(kilometer/hour) = 1000(meters) / 3600(seconds) can also be expressed as 1(kilometer/hour) = 5/18(meters/second), which is its simplified form.
To convert km/h to m/s, directly multiply the given value of speed by the fraction 5/18.
