Lesson: Average SpeedMathematics
In this lesson, we will learn how to calculate the average speed of a particle by dividing the total distance of a journey by its total time.

The table shows the distance covered by a runner at certain times. How far did the runner travel in the first 86 seconds?
|Time in Seconds||0||20||40||60||80||100|
|Distance in Meters||0||50||100||150||200||250|
A body, moving in a straight line, traveled 91 m at 8 m/s. Following this, it traveled at 11 m/s in the same direction for a further 13 seconds. Find the average velocity during the whole trip.
A cyclist traveled 36.5 km from point to point at 36.5 km/h and then traveled a further 22 km in the same direction at 22 km/h. Given that is a unit vector in direction, determine the cyclist’s average speed and average velocity during the whole trip.
