Calculating Speed

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s) or miles per hour (mph).

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

If a runner completes a 100-meter dash in 14 seconds, what is their speed?

Back

Speed = 100 meters / 14 seconds = 7.14 meters/second.

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

How do you calculate average speed from multiple trials?

Back

Add the distances of all trials and divide by the total time taken for all trials.

Front

What is instantaneous speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time.

Front

What is the difference between average speed and instantaneous speed?

Back

Average speed is calculated over a period of time, while instantaneous speed is measured at a specific instant.

Front

What is the formula for calculating distance?

Back

Distance = Speed x Time.

Front

What is the formula for calculating time?

Back

Time = Distance / Speed.

Front

If a car travels at a speed of 80 miles per hour for 180 minutes, how far does it travel?

Back

Distance = Speed x Time = 80 mph x 3 hours = 240 miles.
