18cm * 5km/3cm = 6*5 km = 30 km
1 cm = 10-5 km (or 0.00001 km) So 8.13 cm = 8.13*10-5 km
Well, honey, if 3 cm on the map represents 18 km in real life, then you just need to do a little math. If Riverside and Smithville are 54 km apart in reality, on the map they would be 9 cm apart. So, grab a ruler and start measuring, darling!
If you are talking about metric measurements, 1 cm does not equal 5 km. There are 100,000 cms in a km, so 5 km is actually 500,000 cm To answer your question going along with your assumption that if 1cm = 5 km, there would be 8.5 km in 1.7cm (1.7 x 5 = 8.5)
1 cm = 10-2 metres =10-5 km So, 8.5 cm = 8.5*10-5 km = 0.000085 km
18cm * 5km/3cm = 6*5 km = 30 km
Each cm represents 5 km → 3 × 1 cm : 3 × 5 km → 3 cm : 15 km 3 cm represents 15 km.
You will see a distance of 5 cm on your map represent a 2 km distance across the landscape. Your 2 km is 2,000 meters, and there are 100 cm in a meter. That makes for 200,000 cm in 2 km. If you "reduce" or scale it down by a factor of 40,000, you'll get 200,000 / 40,000 = 5 cm.
1:150,000 means 1 cm on map is represents 150,000 cm or 1.5 km and 1:124,000 means 1 cm represents 124,000 cm or 1.24 km. Likewise, 1:1,000,000 would be a larger area where 1cm of map represents 1,000,000 cm or 10 km on the ground.
It is 20 km * 6.5 = 130 km.
On 1:175,000 scale map one cm on the map represents 175,000 cm (or 1.75 km).
On 1:175,000 scale map one cm on the map represents 175,000 cm or 1.75 km (~1 mile) in the real world.
1 cm = 10-5 km (or 0.00001 km) So 8.13 cm = 8.13*10-5 km
8 cm. No calculator required.

To find the scale:Convert the measurements to the same units (usually the smaller units)drop the unitssimplify1 m = 100 cm 1 km = 1,000 m = 1,000 × 100 cm = 100,000 cmMap scales are given with the map figure, then the real-life figure→ map scale is 1 cm : 1 km (1cm on the map represents 1 km in the real world)= 1 cm : 100,000 cm= 1 : 100,000(This final scale means that 1 whatever measured on the map represents 100,000 of the same whatevers measured in the real world, ie 1mm on the map is 100,000 mm = 100 m in the real world, 1 cm on the map is 100,000 cm = 1 km in the real world, etc.)
1 cm = 10-2 metres =10-5 km So, 8.5 cm = 8.5*10-5 km = 0.000085 km
