- 1. Customary system 2. Metric system
- 1 Kilometer = 1000 meters
1 Meter = 100 centimeters
1 centimeter = 10 millimeters.
- 1 Yard = 3 feet
1 Foot = 12 inches
How many centimeters are equal to 2 Km?
C. 20 000
D. 20 0000
Correct answer is D
Step 1: 1Km = 1000 meters.
2 Km = 1 x 1000 = 2000 meters
Step 2: 1 meter = 100 centimeters
2000 meters = 2000 x 100 = 200 000 centimeters
