Calculating Speed

Front

What is speed?

Back

Speed is the distance traveled per unit of time, usually expressed in units like kilometers per hour (km/h) or meters per second (m/s).

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken. Formula: Average Speed = Total Distance / Total Time.

Front

What is the unit of speed in the metric system?

Back

The unit of speed in the metric system is meters per second (m/s) or kilometers per hour (km/h).

Front

If a car travels 100 km in 2 hours, what is its average speed?

Back

Average speed = Total Distance / Total Time = 100 km / 2 hours = 50 km/h.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, such as 5 m/s north.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (only magnitude), while velocity is a vector quantity (magnitude and direction).

Front

If a runner completes a 400 m track in 50 seconds, what is their speed?

Back

Speed = Distance / Time = 400 m / 50 s = 8 m/s.

Front

What is the average speed of a bus that travels 60 km in 1 hour?

Back

Average speed = Total Distance / Total Time = 60 km / 1 hour = 60 km/h.

Front

How do you convert kilometers per hour to meters per second?

Back

To convert km/h to m/s, divide the speed by 3.6. (1 km/h = 1/3.6 m/s).

Front

What is the average speed of a horse that runs 300 meters in 1 minute?

Back

Average speed = Total Distance / Total Time = 300 m / 60 s = 5 m/s.
