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


Just set up the following proportion: , 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 . . .
