What is the distance between two points if on a plan scale of 1: 10000 it corresponds to 3 cm?

To solve this problem, you first need to translate the indicated scale on the plan from kilometers to centimeters.

Since 1 kilometer is 1000 meters, and 1 meter is 100 centimeters, the scale of the plan in centimeters will be:
1: 100000 = 100000 / (1000 * 100) = 100000/100000 = 1.

It follows from this that 1 centimeter on this plan corresponds to 1 kilometer.

Since the distance between points on the plan is 3 cm, the distance between points on the ground will be:

3 * 1 = 3 km.

Answer: The distance between points is 3 km.
