With this tool, one can calculate the following:

- Speed based on the given distance and time
- Distance based on speed and time
- Time-based on speed and distance

## Calculate Speed

Formula for speed: Distance / Time

## How to find the speed based on distance and time?

**Step 1 : **Select Solve for Speed in the drop down

**Step 2 : **Enter the distance in kilometers (km)

**Step 3 : **Enter the time in hours (hr)

**Step 4 : **Click on **Calculate** button

**Step 5 : **Select the **Show Solution** checkbox to view the calculation

The speed will be displayed in km/hr.

## Example to try for speed calculation

### When the distance covered is 21 km and the time taken is 3 hours, what is the speed?

**Solution : **

\text{Speed}= \frac{\text{Distance}}{\text{Time}}

\text{Speed}= \frac{21}{3}

\text{Speed}= \frac{\text{7 km}}{\text{hr}}

## Calculate Distance

Formula for Distance: \text{Speed} \times \text{Time}

## How to find the distance based on speed and time?

**Step 1 : **Select Solve for Distance in the drop down

**Step 2 : **Enter the speed in km/hr

**Step 3 : **Enter the time in hours (hr)

**Step 4 : **Click on **Calculate** button

**Step 5 : **Select the **Show Solution** checkbox to view the calculation

The distance will be displayed in kilometers.

## Example to try for time calculation

### Q1. When the distance covered is 21 km and the speed is 20 km/hr, what is the time taken?

**Solution : **

\text{Time}= \frac{\text{Distance}}{\text{Time}}

\text{Time}= \frac{21}{20}

\text{Time = 1.05 hr}

A Speed Distance Time (SDT) calculator is a tool that is used to calculate one of the three variables – speed, distance, or time – given the other two variables. It is a useful tool for a wide range of applications, including travel, sports, and transportation. In this article, we will discuss how to use a Speed Distance Time calculator, the formulas used in SDT calculations, and some real-world applications of SDT calculations.

## How to Use a Speed Distance Time Calculator

Using a Speed Distance Time calculator is straightforward. To calculate the missing variable, you need to follow these steps:

**Step 1: Determine the Known Variables **

First, determine which variables you know and which variable you need to calculate. The variables in SDT calculations are speed (S), distance (D), and time (T).

**Step 2: Input the Known Variables**

Input the known variables into the calculator. For example, if you know the speed and the time, input these values into the calculator.

**Step 3: Calculate the Missing Variable
**

The calculator will then calculate the missing variable. For example, if you know the speed and time, the calculator will calculate the distance.

Formulas Used in SDT Calculations

There are several formulas used in SDT calculations. The formulas are as follows:

**Speed Formula**

The formula for speed is:

\text{S}=\frac{\text{D}}{\text{T}}

Where:

S = Speed (in km/h, mph, or m/s) D = Distance (in km, miles, or meters) T = Time (in hours or seconds)**Distance Formula**

The formula for distance is:

\text{S}=\text{D} \times \text{T}

Where:

S = Speed (in km/h, mph, or m/s) D = Distance (in km, miles, or meters) T = Time (in hours or seconds)**Time Formula**

The formula for time is:

\text{S}=\frac{\text{D}}{\text{S}}

Where:

S = Speed (in km/h, mph, or m/s) D = Distance (in km, miles, or meters) T = Time (in hours or seconds)

Real-World Applications of SDT Calculations

SDT calculations are used in a wide range of real-world applications. Here are some examples:

**Travel**

SDT calculations are used in travel to plan the duration of a trip. For example, if you know the distance you need to travel and the speed at which you will travel, you can use an SDT calculator to calculate the time it will take to reach your destination.**Sports**

SDT calculations are used in sports to measure the performance of athletes. For example, if you know the distance an athlete has covered and the time it took, you can use an SDT calculator to calculate their speed.**Transportation**

SDT calculations are used in transportation to optimize routes and schedules. For example, if you know the distance between two locations and the speed at which a vehicle can travel, you can use an SDT calculator to calculate the time it will take to reach the destination.**Physics**

SDT calculations are used in physics to study the motion of objects. For example, if you know the distance an object has traveled and the time it took, you can use an SDT calculator to calculate the object’s speed.

## Conclusion

A Speed Distance Time calculator is a useful tool for calculating one of the three variables – speed, distance, or time – given the other two variables. By understanding how to use a Speed Distance Time calculator and the formulas used in SDT calculations, you can apply them to real-world scenarios to solve problems and optimize processes. SDT calculations are used in a wide range of applications, from travel and transportation to sports and physics, and they are an essential tool for understanding the world around us.
