Something looks odd about number two...

speed vs velocity

 

speed is distance/time

velocity is displacement/time

 

imagine running a mile out and a mile back in 20 minutes. your avg speed would be 10min/mile. your avg velocity would be 0.

 

so the answer, even though this is like 3 months old:

 

if dx=0 and dt=/=0 and velocity = dx/dt = 0/some number = 0

if dx =/= 0 and dt=0 and velocity = dx/dt = some number/0 = ?

 

graphically, the first part would be a horizontal line graphed as y=0 and x>0

the second part would be a vertical line graphed as x=0 and y>0
