how can you explain that 2 cm. reprecents 500km.
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
1:50,000. This means that 1 unit measured on the map represents 50,000 units in the real world. So if you measure 1 cm on the map, then it represents 50000 cm, which is 500 meters or 0.5 km. So 2 cm on the map represents 1 km. If you measure 1 inch on the map, then that represents 50,000 inches, which is about 4167 feet or 0.79 miles.
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
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 .
