A woman and her dog are out for a morning run to the river, which is located 4.2 km away. the woman runs at 2.2 m/s in a straight line. the dog is unleashed and runs back and forth at 4.0 m/s between his owner and the river, until the woman reaches the river. what is the total distance run by the dog?

Respuesta :

distance between woman and river is 4.2 km

speed of the woman = 2.2 m/s

now the time taken by the woman to reach the river is given as

[tex]t = \frac{d}{v}[/tex]

[tex]t = \frac{4200}{2.2}[/tex]

[tex]t = 1909.1 s[/tex]

now we have to find the distance covered by the dog in the same time

[tex]d = v_{dog} * t[/tex]

[tex]d = 4 * 1909.1[/tex]

[tex]d = 7636.4 m = 7.636 km[/tex]

so the distance covered will be 7.636 km
