## How do you calculate the average speed?

Average speed can be calculated by taking the distance covered and subtracting its time to travel the same distance.

## Average speed formula

the average speed of any moving object can be calculated using the basic formula below:

𝑉 = ∆𝑠 / ∆𝑡 = 𝑠2 − 𝑠1 / 𝑡2 − 𝑡1

𝑉: Average speed

S.I. unit: m/s, alternative unit: km/h

∆𝑠: Distance traveled

S.I. unit: m, alternative unit: km

∆𝑡: Time

S.I. unit: s, alternative unit: h

s1,s2: Distance traveled by the body along the trajectory starting at the beginning of motion s1, and the movement began at the beginning s2.

S.I. unit: m, alternative unit: km

t1, t2: The time when the body is located at its initial point s1 The last point s2 respectively.

S.I. unit: s, alternative unit: h

## Speed units

The unit of measurement for velocity in the International System (S.I.) is meter per second (m/s). However, the kilometer per hour (km/h) unit is also used in some cases. This is evident when we speak of a car's speed, which is always expressed in kilometers per hour.

km/h to m/s: multiply the speed value by 3,6

m/s to km/h: divide the speed value by 3,6

## What is velocity?

Let's take the speed definition to describe velocity. Speed is the speed at which something moves. Speed is the speed of a vehicle, but velocity also includes direction. For example, a runner running at 9km/h talks about their speed. However, if they are running eastwards at 9km/h, their velocity has an obvious direction.

## What is the speed of light?

Light travels at a speed of 299,792,458 m/s.

## What is the speed of sound?

Sound travels at 343 m/s in dry air at 20° C.
