After 5 Hence it is unsafe to drive at a speed 72 km/hr. In general, the formula relating distance, rate, and time is (9.11.1) d i s t a n c e = r a t e t i m e Definition: Distance, Rate and Time For an object moving in at a uniform (constant) rate, the distance traveled, the elapsed time, and the rate are related by the formula (9.11.2) d = r t where d = distance, r = rate, and t = time. Let's assume that the distance between the PM view and the S is the average speed. Do not solve. Therefore if we let: d =distance travelled r =rate of speed the car is traveling t =time the car has been traveling. G0 * Running at an average rate of 8 m/s, a sprinter ran to the end of a track and then jogged back to the starting point at an average of 3 m/s. Let's say this is the point B, and this is the point of view, and here to here is gone. 2. How do you evaluate variable expressions? 3.
