A bus traveled in a straight line for 3.2hours, with an average velocity of 88km/h. The bus stopped for 20 minutes, and then went south for 2.8hours at an average velocity of 75km/h. What is the average velocity for the ENTIRE trip (including when they stopped - it'd total 6.333 hours)?
What is the displacement for the ENTIRE trip?
Can someone help me with these 2 questions? I wouldn't normally ask but when you have a substitute that knows nothing about what you're learning it's hard to understand it!!
Thanks in advance....

The straight line was going in an easterly direction.
I need help finding the average velocity and displacement...

What direction was the straight line, East?
If East, then easterly displacement is
88*3.2 km
South
75*2.8 km
the total displacement is
sqrt(East^2+South^2)
