### Speed distance time Calculator

## What is Speed?

Speed is defined as the rate of change in distance with respect to time. It is a scalar quantity. Only magnitude is required to define the speed.
SI unit of Speed is m/s

Average speed is defined as

$s= \frac {\text{distance}}{\text{time}}$

or

$s= \frac {d}{t}$

Where

s -> Average Speed

d -> Distance travelled

t -> time taken

This is called speed distance time formula.

__ Some Important Unit conversions__
1 Km = 1000 m

1 hour= 60 min = 3600 sec

1 km/hr = 5/8 m/s

**Example of Few questions where you can use this speed distance time Calculator**

**Question 1**

A Body travels a distance 60 km in 2 hour.Find the Speed of the body in m/s

**Solution**

Given d = 60 km = 60000 m, t= 2 hour =7200 sec, s=?

Now Speed is given by the formula

$s= \frac {d}{t}$

$s = \frac { 60000}{7200}= 8.33 \ m/s$

**Question 2**

A object travels a distance 1000 m with the speed 50m/s . Find the time taken by the object.

**Solution**

Given d = 1000 m , t=?, s=50 m/s

Now Speed is given by the formula

$s= \frac {d}{t}$

Rearranging this for time

$t = \frac {d}{s}$

$t = \frac { 1000}{50} = 20 \ s $

**Question 3**

A object moves with the speed 50m/s for 10 min. Find the distance travelled by the body.

**Solution**

Given d = ? , t=10 min = 600 sec, s=50 m/s

Now Speed is given by the formula

$s= \frac {d}{t}$

Rearranging this for distance

$d = s \times t $

$d = 50 \times 600 = 30000 \ m=30 \ km $

## How the Speed distance time Calculator works

1. If distance and time given

$s =\frac {d}{t}$

2. If distance and speed are given

$t= \frac {d}{s}$

3. If time and speed are given

$d = s \times t$
