Younger boys:, Q:The perimeter of a triangle is 46 centimeters. A family drove to a resort at an average speed of 30 km/h and later returned over the same road at an average speed of 50 km/h. On major urban highways, slow-moving traffic is common (Figure 1). 1. Two small planes start from the same point and fly in opposite directions. The total distance the car traveled would be 100 miles, and the amount of time it spent traveling would be 4 hours. 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 . Distance, rate and time problems are a standard application of linear equations. If Jerry rides at the rate of 20 km/h, at what rate must Susan ride if they are 150 kilometres apart in 5 hours? distance = time into downstream speed + time into upstream speed =(speed-3) + 30/60 (speed+3). The rate of Peter will be x + 10. 97% of Numerade students report better grades. 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.
