Question

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

Answer 1

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 = $\frac{displacement}{time}$

From the given question,

Displacement = $\sqrt{200^{2} + 375^{2} }$

                       = $\sqrt{40000+140625}$

                       = $\sqrt{180625}$

                       = 425

The displacement of woman is 425 miles.

velocity = $\frac{425}{11.75}$

             = 36.1702 miles/hour

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