To find the actual distance on the ground, we will use the map scale, which is 1 : 25,000. This means that 1 cm on the map represents 25,000 cm in reality.

1. Convert the map measurement to the real distance:

   $\text{Actual distance} = 10 \text{cm} \times 25,000 = 250,000 \text{cm}$

2. Convert centimeters to kilometers:

   Since there are 100,000 cm in a kilometer:

   $\text{Distance in kilometers} = \frac{250,000 \text{cm}}{100,000} = 2.5 \text{km}$

The distance covered on the ground is 2.5 km, which is already to two significant figures.

Here are five related questions:

1. How would the calculation change if the map scale was 1 : 50,000?
2. What is the distance in meters instead of kilometers?
3. How do you convert different map scales to real distances?
4. If the scale was 1 : 10,000, how far would 10 cm on the map be on the ground?
5. What if the measurement was in inches; how would the conversion proceed?

Tip: Always ensure that units are consistent throughout your calculations to avoid errors.
