1 kilometer=
a)1,000centimeters
b)1,000,000millimeters
c)10 meters
D)10,000centemeters
e)100meters
I will be happy to critique your logic on this.
100 meters
The prefix kilo- means 1,000.
kilo + meter = ??
so the answer would be a?
To convert 1 kilometer to different units of length, you can use the following conversion factors:
1 kilometer = 1,000 meters
1 meter = 100 centimeters
1 meter = 1,000 millimeters
Now let's go through each option:
a) 1 kilometer = 1,000 centimeters. This is a valid conversion because 1 kilometer equals 1,000 meters, and 1 meter equals 100 centimeters. You can calculate this by multiplying 1 kilometer by 1,000 (conversion factor from meters to centimeters).
b) 1 kilometer = 1,000,000 millimeters. This is correct because 1 kilometer equals 1,000 meters, and 1 meter equals 1,000 millimeters. You can calculate this by multiplying 1 kilometer by 1,000 (conversion factor from meters to millimeters), and then multiplying by an additional 1,000 (conversion factor from kilometers to meters).
c) 1 kilometer = 10 meters. This is incorrect because it assumes that 1 kilometer is equal to 10 meters. However, the correct conversion is 1 kilometer = 1,000 meters.
d) 1 kilometer = 10,000 centimeters. This is incorrect because it assumes that 1 kilometer equals 1,000 meters, and then multiplies by 10. However, the correct conversion is 1 kilometer = 1,000 meters = 100,000 centimeters.
e) 1 kilometer = 100 meters. This is incorrect because it assumes that 1 kilometer is equal to 100 meters. However, the correct conversion is 1 kilometer = 1,000 meters.
Therefore, the correct conversions are:
a) 1 kilometer = 1,000 centimeters (option a)
b) 1 kilometer = 1,000,000 millimeters (option b)
