If possible, classify the entries in the list below as: an English noun, or a mathematical expression, an English sentence, or a mathematical sentence. Therefore if we let: Then, assuming the car is traveling at a constant rate of speed the equation would be "d =rt", This site is using cookies under cookie policy .
