Phyllis decides she is going to on a bus
tour of the city. The bus starts by traveling
300 m West in 8 minutes. It then stops for 1
minute for pictures, before heading
another 200 m East in 6 minutes. It stops
again for a 5 minute stretching break, and
then goes back 400 m West in 10 minutes.
What is the average speed and average
velocity of the bus, in meters per second?
