What is the length of the segment representing the distance on the ground 1 km, on the map

What is the length of the segment representing the distance on the ground 1 km, on the map, if the scale of the map is 1) 1: 100000 2) 1: 50000 3) 1: 25000

If it is said that the scale of the map is 1: 100000, then this means that 1 cm on the map corresponds to 100000 cm or 1 km on the ground. Therefore, 1 km on a map with a scale of 1: 100000 is a segment 1 cm long.
At a scale of 1: 50,000, 1 cm on the map corresponds to 50,000 cm or 0.5 km on the ground. Therefore, 1 km on a map with a scale of 1: 50,000 is a 2 cm long segment.
Similarly, at a scale of 1: 25000, 1 cm on the map corresponds to 25000 cm or 0.25 km on the ground. Therefore, 1 km on a map with a scale of 1: 25000 is a segment 4 cm long.
