If (D) is distance travelled and (R) is the rate of travel, which of the following represnts the relationship between (D) and (R) for the equation d-2r

A. D is twice as much as R

B. R is twice as much as D

C. D is two more than R

D. R is two more than D

Step-by-step explanation:

I'm thinking that's supposed to be d = 2r, not d - 2r?

If that's the case, start with the d. Then move to the equals sign, which represents the word "is" in mathspeak. So far we have "d is". 2r is twice as much as r, or twice r.

d = twice as much as r

So A is your choice.
