A woman and her dog are out for a morning run to the river, which is located 3.80 km away. The woman runs at 3.65 m/s in a straight line. The dog is unleashed and runs back and forth at 5.33 m/s between his owner and the river, until she reaches the river. What is the total distance run by the dog (in meters)?
The total time: t = Sw / Vw. So, the total distance run by the dog is Sd = Vd * t = 5.33 * 3800 / 3.65 = 5549.04 m. Answer: 5549.04 m.
