Train A and train B leave a central station at the same time. They travel the same speed, but in opposite directions, with train
A heading towards station A, and train B heading towards station B. Train A reaches station A after 2 1/2 h. Train B reaches station B after 4 h. Station A and B are 585 mi apart. What is the rate of the trains?
I believe it is B, as C and D both are based on the number of books sold while the only variable to determine the amount of money she earns are the additional doors she knocks on.
