# Speed Calculation: How to Calculate the Speed of an Object

What does the expression (5.6x10^-7m)/(2.8x10^-12s) represent and what is the final answer?

The expression (5.6x10^-7m)/(2.8x10^-12s) represents a calculation of speed equal to 200,000 m/s.

## Understanding Speed Calculation

**Explanation:** The problem above represents the division of a distance measurement (in meters) by a time measurement (in seconds), which results in a calculation of speed or velocity. When we divide 5.6x10^-7m by 2.8x10^-12s, we get the final answer of 200,000 m/s. This means that the object or particle is moving at a speed of 200,000 meters per second. The significant digits have been maintained in this calculation.

## Further Explanation

**More about Speed Calculation:** Speed is a measurement of how quickly an object moves from one place to another. It is calculated by dividing the distance traveled by the time it took to travel that distance. In the given expression, the distance is 5.6x10^-7 meters and the time is 2.8x10^-12 seconds. By dividing these values, we arrive at a speed of 200,000 m/s.

Speed calculation is essential in various fields, including physics, engineering, and everyday life. Understanding how to calculate speed helps us analyze how fast objects move and can be crucial for tasks such as designing transportation systems, analyzing the motion of celestial bodies, and predicting the speed of moving vehicles.
