What are the three types of map scales?
Linear, Verbal, and Representative ratio scale.
Put scales in order from smallest to largest: 1:20 000, 1:1 000 000, 1:100 000
1:1 000 000, 1:100 000, 1:20 000
The scale on a map is 1cm to 50km. If the distance on the map is 8cm, then what is the real land distance?
400km because as there is 8cm, and 1cm is equal to 50km, 50 * 8 = 400.
How many cm are there in a m?
100 000 000cm
How many m are there in a km?
1000m
