The formula for how far a moving object travels in terms of the rate, or speed at which it moves, and the travel time, or how long it is moving, is d = rt, where d stands for distance, r stands for rate, and t stands for time. Rearrange the quantities in this formula to give a new formula for travel time in terms of distance and rate of travel. A. t=rd B. t=d/r C. t=r/d D. t=d−r
