A boat is traveling upstream at 14 km/h with respect to the water of a river. The water itself is flowing at 9 km/h with respect to the ground. What is the velocity of the boat with respect to the ground

Respuesta :

Answer:

16.64 km/h

Explanation:

Think of the x and y components as the a and b sides of a triangle and simply do the Pythagorean Theorem:

[tex]a^2+b^2=c^2[/tex]

[tex]14^2+9^2=c^2[/tex]

[tex]\sqrt{196+81}=c[/tex]

[tex]\sqrt{277}=c[/tex]

[tex]16.64 km/h[/tex]
