Set up a ratio:
0.5cm / 2km = X cm/120 km
Cross multiply:
2X = 0.5 x 120
2x = 60
Divide both sides by 2
X = 60 /2
X = 30 cm
Answer:
30 CM
Step-by-step explanation:
Note that 0.5 centimeter = 2 kilometer.
Find the amount of kilometers that equal one centimeter.
(0.5)(2) = (2)(2)
1 centimeter = 4 kilometer.
Divide 120 with 4 to get the amount of centimeters.
120/4 = 30
30 CM is your answer.
