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

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

Step-by-step 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 =
`(displacement)/(time)`

From the given question,

Displacement =
`\sqrt{200^(2) + 375^(2) }`

=
`√(40000+140625)`

=
`√(180625)`

= 425

The displacement of woman is 425 miles.

velocity =
`(425)/(11.75)`

= 36.1702 miles/hour

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