While loading, a truck moves 10 meters west from point A to point B in 5 seconds. Then it moves back to point A in 5 seconds. What are the average speed and average velocity of the truck?

Av speed is 2m/s and the Av velocity is 0 m/s2

Explanation: For speed it is distance over time so 20/10 which equals 2 and velocity is displacement over time or second position minus the first position over time. So 10m minus 10m is 0m. So the equation would be 0/10 which is just 0.

it has to be b, about 97 percent.

find the sum of the two horizontal vectors and the sum of the two vertical vectors
