What Is the Spider's Average Speed and Magnitude of Average Velocity?

[BriannaUND]

I am having a problem with the following question:
A spider crawls from corner A to corner B in 30 minutes. The distance between AC (C chosen as a half-way point) is 27 meters, the spider turns right and the distance between CB is 21 meters. a) What is its average speed? and b) what is the magnitude of its average velocity?
Thanks for any help!

For average speed, divide the distance traveled by the time; for average velocity, divide the displacement by the time.
