2 km
50 centimeters or 500 millimeters or 1.64 feet1/2 meter:= 1/2 m * 100 cm/1 m = 50 cm=1/2m*1000 m/1m = 500 mm=1/2m*3.28 ft/1m = 1.64 ft
There are 500 metres in 1/2 of a km
20 nm = 500 × 10^-9 m 2 cm = 2 × 10^-2 cm → 2 cm ÷ 500 nm = (2×10^-2 m) ÷ (500 × 10^-9 m) = (2÷500) × 10^(-2 - -9) = 0.004 × 10^7 = 4 × 10^4 = 40,000
Convert the units of both sides to the same, then remove the units and simplify (if possible by dividing both sides by a common divisor greater than 1). eg The Landranger series map scale of 2 cm equals 1 km: 1 m = 100 cm 1 km = 1,000 m → 1 km = 1,000 x 100 cm = 100,000 cm 2 cm : 1 km → 2 cm : 1 x 100,000 cm → 2 cm : 100,000 cm → 2 : 100,000 → 1 : 50,000
1 meter is 100 cm. 500 cm is 500 cm. 2 meters is 200 cm. Therefore, 500 cm is the longest distance.
20 km is 2 million cm
2 km
One km is 100,000 cm, therefore 2*100,000 is 200,00 cm. 2km is 200,000cm.
500 m = 0.5 km = 1/2 km
9000 cm = 0.09 km and is less than 2 km
A 1 to 50,000 scale map means that one unit on the map represents 50,000 of the same units on the ground. For example, one centimeter on the map would represent 50,000 centimeters (500 meters) on the ground. The physical size of the map would depend on the area covered by it but is typically larger than a regular piece of paper.
2 km is greater.
2 km = 2*105 cm
1 km = 1000 m and 1 m = 100 cm, so 1 km = 100000 cm 2 km = 200000 cm ■
For determining which is the bigger unit we have to relate both the units to each other . we know, 1 km =100000 cm. 2 km =200000 cm which is greater than 9000 cm.
first lets find out the relation between cm and km . the relation is 1 km=100000 cm. 2 cm =0.00002 km . now finding the ratio of 2 cm to 1000 km . 0.00002 : 1000 = 2 : 10 ^ 8 = 1 : 10 ^ 8 /2 .
