Answer 1

the answer is A which comes out to about 160812 cm

Answer 2

`A. (5280*12)/(0.394)cm`

Step-by-step explanation:

1. Take the quantity you want to convert:

`1mile`

2. Multiply by the first conversion factor:

`1mile*(5280feet)/(1mile)`

3. Apply the second conversion factor:

`1mile*(5280feet)/(1mile)*(12inches)/(1foot)`

4. Multiply by the third conversion factor:

`1mile*(5280feet)/(1mile)*(12inches)/(1foot)*(1centimeter)/(0.394inches)`

5. Multiply all the numerators and divide by denominators:

`1mile*(5280feet)/(1mile)*(12inches)/(1foot)*(1centimeter)/(0.394inches)=(5280*12)/(0.394)cm`
