Sofia goes on a hike on a trail that is 10 km long. She starts at 2:00pm and ends at 5:00pm. The end of the trail is 300m north of the beginning of the trail. What is Sofia's average velocity? (Velocity= displacement/time) Question 12 options: 100 m/hr S 30 m/hr S. 01 m/hr S 3. 3 m/hr S.

Respuesta :

As the question depicts the trail is 10Km long but the end of the trail is 300m north from the beginning, Here the average velocity comes out to be 100m/hr.

What is Velocity?

Velocity is defined as the displacement covered by an object or a body in unit time interval.

From the problem, it is clear that the distance is 10Km but the displacement comes out to be 300m.

The time from 2:00 pm to 5:00 pm is a total of 3hours.

Now, the velocity is determined from the following formula

[tex]V=\dfrac{d}{t}[/tex]

here,

d= displacement

t= time

So, by putting values in above formula we get,

[tex]V=\dfrac{300 m}{3 hrs}[/tex]

[tex]V=100m/hr[/tex]

So, the average velocity of Sofia is 100m/hr
