Answer 1

To find an average velocity, you need a distance and a time.
What distance was traveled in part C?
How much time did it take to travel part C?
Then divide the distance by the time to find the average velocity.

Answer 2

So 6 divided by 90?

Answer 5

Where did you get 90 from?
6 is correct. You need to divide 6 miles by a time.
What was the time used for travel in part C?

Answer 6

How much time is there between 9:45 am and 10:45 am?

Answer 7

Oh well I chose A as my answer and i thought there was 90 minutes between 9:45 and 10:45

Answer 8

Really?
Isn't it exactly 1 hour between 9:45 am and 10:45 am?
And isn't 1 hour 60 minutes, not 90?
Also, the choices have all velocities in km/h. There are no minutes there, so keep the time in hours. Don't convert to minutes.
6 km in 1 hour = 6 km/h
Since the direction is west, answer is 6 km/h west
