Calculating Speed: Distance, Time, and Equations

This video tutorial explains how to calculate the speed of an object using the distance traveled and the time taken. It introduces the basic formula for speed calculation and demonstrates it with examples, including an athlete running and a car traveling a certain distance. The tutorial also covers how to calculate average speed for a journey, converting units as necessary, and provides a step-by-step guide to using the formulas effectively.

What does it mean when an athlete runs at 2 meters per second?

• The athlete runs 4 meters every second.

• The athlete covers 2 meters every second.

• The athlete covers 2 meters in 2 seconds.

• The athlete runs 2 meters in 4 seconds.

Which equation represents the speed of an object?

• Speed = Distance / Time

• Speed = Time / Distance

• Speed = Time x Distance

• Speed = Distance x Time
