It's not RATE of SPEED. It's either rate or speed....one or the other.





Just set up the following proportion: matrix%281%2C3%2C+105%2FD%2C+%22=%22%2C+.5%2F1.25%29, with D being distance.

Now solve this for D, the distance you're looking for.

Never use the term "rate of speed".


There is "rate" and there is "speed".


When applied to a rectilinear movement, they denote the same conception.


But the combination  "rate of speed" is NEVER USED  and means  NOTHING.


It only reveals that you don't know terminology; so be accurate and watch your terminology . . .
