Speed = Distance/Time: Explained

  • Thread starter usernameee

In summary, the conversation discusses the concept of average speed and its formula, v = d/t, which can also be expressed as v = d*t. The use of "per" in everyday language is equivalent to the mathematical symbol "/". This formula can be used to measure speed in different units, such as meters per second or miles per hour.

Why dose v = d/t ?

Did you have some specific problem in mind?

Average speed, by definition, equals distance/time.

so, it could be also: v = d*t ?

No. Those are not equivalent at all.

Think how speed would be measured: meters per second, m/s, for example.

why did you replace per with / ... ?

That's what it means. I just translated everyday language into the more precise mathematical language.

If your speed is 60 miles per hour, you can write that as 60 miles/hour.

I got it... Thanks!
 

1. What is the formula for calculating speed?

The formula for calculating speed is Speed = Distance/Time, where speed is measured in units of distance per unit of time.

2. How do you determine the distance traveled?

The distance traveled can be determined by multiplying the speed by the time traveled. For example, if you travel at a speed of 60 miles per hour for 2 hours, the distance traveled would be 120 miles.

3. How does time affect speed?

Time and speed are inversely proportional. This means that as time increases, speed decreases and vice versa. For example, if you travel a distance of 60 miles in 1 hour, your speed would be 60 miles per hour. But if you travel the same distance in 2 hours, your speed would be 30 miles per hour.

4. What are the units of measurement for speed?

The units of measurement for speed can vary depending on the system used. In the metric system, speed is typically measured in meters per second (m/s), while in the imperial system, it is measured in miles per hour (mph) or feet per second (ft/s).

5. Can you calculate speed if distance and time are not given?

No, speed cannot be calculated if distance and time are not given. The formula for speed requires both distance and time to be known in order to calculate the speed accurately.
