Question

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)?

Answer 1

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.
