Jake and brenda drove at a speed of 30 miles for one hour then they turned around and drove 45 miles per hour until they were back where they started what is the true or what is true about their average speed and average velocity

Average speed is greater than average velocity. Average velocity is zero.

Explanation:

Average speed is calculated by:

Distance is the length of the total path traveled.

Average velocity is given by:

Displacement = final position - initial position.

Since, final position =initial position, Displacement = 0, therefore, average velocity = 0

It can be concluded that average velocity is zero and average speed is greater than average velocity.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
