To calculate the speed, you can use the formula:

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

Given:

• Distance = 200 meters
• Time = 25 seconds

Substitute these values into the formula:

$\text{Speed} = \frac{200 \, \text{m}}{25 \, \text{s}} = 8 \, \text{m/s}$

So, Mina's speed is 8 meters per second.

Would you like more details or have any questions about this?

Here are a few related questions:

1. How does speed relate to velocity in this scenario?
2. What would Mina's speed be if she ran the same distance in 20 seconds?
3. What is the formula for calculating speed when distance and time are not directly provided?
4. How would the speed change if Mina ran 400 meters in 50 seconds?
5. How do you convert speed units from meters per second to kilometers per hour?

Tip: Speed is a scalar quantity, meaning it only considers magnitude (how fast something is moving), not direction.
