Final answer:
To find the actual distance between two places on a map with a scale of 1 cm:2500m, multiply the map distance of 3.5 cm by 2500 m/cm, resulting in an actual distance of 8750 meters.
Step-by-step explanation:
To determine the actual distance between two places on a map when given the scale and the map distance, you can set up a proportion. For a map scale of 1 cm:2500m, and a map distance of 3.5 cm, you multiply the map distance by the scale factor.
First, write the scale as a ratio (1 cm / 2500 m).
Now, multiply the map measurement by the actual distance for each centimeter on the map:
3.5 cm × 2500 m/cm = 8750 m
Therefore, the actual distance between the two places is 8750 meters.
