To solve this problem, we will use the proportioning. Let’s denote by x the given distance on the ground.
Let’s make the following proportion:
1 cm = 50,000;
5 cm = x;
Let’s solve this proportion using the method of diagonals, multiplying each diagonal with each other.
1 * x = 5 * 50,000;
Let’s sort this equation by performing the possible multiplication actions:
1 * x = 250,000;
x = 250000 cm = 2500 meters = 2.5 km.
Answer: the length of this distance on the ground is 2.5 km.
