How do you find an average for the speed of somthing

Answer 1

To find the average speed of an object or a journey, you can use the following formula:

\[
\text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}}
\]

Here’s how to apply this formula step by step:

1. **Measure the Total Distance**: Determine the entire distance traveled by the object. This could be in kilometers, miles, meters, etc.

2. **Measure the Total Time**: Determine the total time taken for the journey. This could be in hours, minutes, seconds, etc.

3. **Convert Units if Necessary**: Ensure that the distance and time are in compatible units so that the average speed is expressed in a meaningful unit (e.g., kilometers per hour, miles per hour).

4. **Perform the Calculation**: Divide the total distance by the total time to get the average speed.

### Example:
Suppose a car travels 150 kilometers in 2 hours.

- Total Distance = 150 km
- Total Time = 2 hours

Now, calculate the average speed:

\[
\text{Average Speed} = \frac{150 \text{ km}}{2 \text{ hours}} = 75 \text{ km/h}
\]

So, the average speed of the car is 75 kilometers per hour.
