Distance = Speed x Time

Distance = Time x Speed

Speed = Distance x Time

Time = Speed x Distance

Time = Distance/Speed

Time = Speed/Distance

Distance = Time x Speed

Speed = Time x Distance

Speed is a scalar quantity while velocity is a vector quantity.

Velocity is a scalar quantity while speed is a vector quantity.

Both speed and velocity are scalar quantities.

Both speed and velocity are vector quantities.

Distance is the total path traveled while displacement is the straight-line distance between the starting and ending points.

Distance and displacement are the same thing.

Distance is the straight-line distance between the starting and ending points while displacement is the total path traveled.

Distance and displacement are both scalar quantities.

Instantaneous speed is the speed at a particular moment while average speed is the total distance traveled divided by the total time taken.

Instantaneous speed is the speed over a long period of time while average speed is the speed at a particular moment.

Instantaneous speed and average speed are the same thing.

Instantaneous speed is the speed at the start of motion while average speed is the speed at the end of motion.
