Speed Calculator
Calculate your speed based on distance and time.
What is Speed?
Speed is a scalar quantity that measures how fast an object is moving. It is defined as the distance traveled per unit of time. In simpler terms, speed indicates how quickly an object covers a distance. It is commonly expressed in units like kilometers per hour (km/h) or miles per hour (mph). Understanding speed is crucial for various reasons:
- Transportation: Knowing your speed can help you manage travel time and fuel efficiency.
- Sports: Athletes often track their speed to improve performance.
- Daily Activities: Understanding your speed can enhance your daily planning, whether walking, biking, or driving.
Relationship Between Speed, Distance, and Time
The relationship between speed, distance, and time can be expressed through simple calculations. Here’s how they interconnect:
- Speed Calculation:
- Speed is calculated by taking the total distance traveled and dividing it by the total time taken to cover that distance.
- In common wording: Speed is equal to the distance divided by the time.
- Formula:
- Speed = Distance ÷ Time
- Distance Calculation:
- To find out how far something has traveled, multiply the speed by the time.
- In common wording: Distance is equal to the speed multiplied by the time.
- Formula:
- Distance = Speed × Time
- Time Calculation:
- If you want to know how long it took to travel a certain distance, divide the distance by the speed.
- In common wording: Time is equal to the distance divided by the speed.
- Formula:
- Time = Distance ÷ Speed
Understanding these relationships allows you to easily calculate any of the three variables if you have the other two.
Common Speed Units
Speed can be expressed in various units, each suited to different contexts. Here are some common speed units along with their conversions:
| Unit | Symbol | Equivalent |
|---|---|---|
| Kilometers per hour | km/h | 1 km/h = 0.621371 mph |
| Miles per hour | mph | 1 mph = 1.60934 km/h |
| Meters per second | m/s | 1 m/s = 3.6 km/h |
| Feet per second | ft/s | 1 ft/s = 0.681818 mph |
Understanding these units will help you interpret speed measurements in various contexts.
Examples of Different Speeds
Different activities have different typical speeds. Below are some examples that illustrate a range of speeds you might encounter:
| Activity | Speed (km/h) | Speed (mph) |
|---|---|---|
| Walking | 5 | 3.1 |
| Jogging | 10 | 6.2 |
| Cycling | 20 | 12.4 |
| Driving in the city | 50 | 31.1 |
| Highway driving | 100 | 62.1 |
| Commercial airplane | 800 | 497.1 |
| Speed of sound | 1235 | 767.3 |
These examples demonstrate how speed varies greatly depending on the activity, helping you gauge what is considered a “fast” or “slow” speed in different scenarios.
