Average Speed and Velocity

What is the formula to calculate average speed?

• total distance + total time

• total distance * total time

• total distance - total time

• total distance / total time

A car travels a distance of 200 km in 4 hours. What is its average speed?

• 40 km/h

• 100 km/h

• 50 km/h

• 60 km/h

What is the formula to calculate average velocity?

• average velocity = total distance / total time

• average velocity = total displacement * total time

• average velocity = total displacement / total time

• average velocity = total displacement + total time

A train travels 500 meters north in 2 minutes. What is its average velocity?

• 100 meters per minute

• 400 meters per minute

• 600 meters per minute

• 250 meters per minute

What is the main difference between speed and velocity?

• Speed and velocity are the same thing.

• Speed is measured in kilometers per hour and velocity is measured in meters per second.

• Speed is the rate at which an object moves and velocity is the rate at which an object changes its position.

• The main difference between speed and velocity is that speed is scalar and velocity is vector.
