23 centimeters =
We make the following rule of three:
1 centimeter ----> 1 kilometer
23 centimeter -> x kilometer
We clear x:
x = (23/1) * (1)
x = 23 kilometers
0.5 centimeters =
We make the following rule of three:
1 centimeter ----> 1 kilometer
0.5 centimeter -> x kilometer
We clear x:
x = (0.5 / 1) * (1)
x = 0.5 kilometers
9 centimeters =
We make the following rule of three:
1 centimeter ----> 1 kilometer
9 centimeter -> x kilometer
We clear x:
x = (9/1) * (1)
x = 9 kilometers
Answer:
c. 23 kilometers
a. 0.5 kilometers
b. 9 kilometers
It is 1,200,000,000, according to this calculator
Answer:
120 mph
Step-by-step explanation:
Distance = rate * time
D = 70 miles
t = 35 minutes
So that gives us:
70 mi = r(35 min)
Divide both sides by 35 min:
70/35 mi/min = r
simplify:
2 mi/min = r
If you wish to convert to miles per hour, remember that there are 60 minutes in an hour:
2 * 60 = 120
120 mph = r
