RT=D for travel rates and distance

___________________speed___________time_________distance
AGNST______________r-25____________t+2___________375
WITH_______________r+25____________t_____________375


system%28%28r-25%29%28t%2B2%29=375%2C%28r%2B25%29%2At=375%29

You will need two substitutions during to solving process involving rt.
