To calculate the speed, we can use the formula for speed:

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

Given:

• Distance = 78 meters
• Time = 12 seconds

$\text{Speed} = \frac{78 \, \text{meters}}{12 \, \text{seconds}} = 6.5 \, \text{m/s}$

Answer:

The speed is 6.5 meters per second (m/s).

Would you like me to provide details or explore further? Here are some related questions:

1. What is the speed in kilometers per hour (km/h)?
2. How long would it take to travel 100 meters at this speed?
3. What is the acceleration if the object starts from rest?
4. What is the total distance covered if the speed is maintained for 30 seconds?
5. How can speed be converted to different units, such as feet per second?

Tip: Always keep an eye on unit conversions when working with speed, distance, and time.
