The length of the segment on the map is 3 cm. Find the length of the corresponding one

The length of the segment on the map is 3 cm. Find the length of the corresponding one on the spot if the scale of the map is 1: 1000000

If the scale of the map is 1: 1,000,000, then 3 cm of the length of the segment on the map will be equal to 3,000,000 cm.Let us first translate into meters (1 m = 100 cm) 3,000,000 cm = 30,000 m, then into kilometers (1 km = 1,000 m) 30,000 m = 30 km.
Answer: a 3 cm segment on the map is equal to a 30 km segment on the ground.
