A woman drives 200 miles west and then turns south and drives 375 miles. Her trip takes her 11.75 hrs. What is the woman's average Velocity during the trip

Respuesta :

Answer:

The woman's average velocity during the trip is 36.2 miles/hour.

Explanation:

Velocity can be define as the displacement of an object per time. It is a vector quantity, and measured in m/s.

i.e velocity = [tex]\frac{displacement}{time}[/tex]

From the given question,

Displacement = [tex]\sqrt{200^{2} + 375^{2} }[/tex]

                       = [tex]\sqrt{40000+140625}[/tex]

                       = [tex]\sqrt{180625}[/tex]

                       = 425

The displacement of woman is 425 miles.

velocity = [tex]\frac{425}{11.75}[/tex]

             = 36.1702 miles/hour

The woman's average velocity during the trip is 36.2 miles/hour.
