Answer:

a. 12.4 mi

Step-by-step explanation:

Hello

this is a unit conversion problem,you must know the equivalence

in this case

1 mi. ≈ 1.61 km.

Now, we need to convert 20 Km into miles

we can use a simple rule of three

1 mi.  ⇔ 1.61 km

x mi.  ⇔ 20 Km

[tex]\frac{x (mi)}{20 Km} =\frac{1 mi}{1.61 Km} \\\\Now\ isolating\ x\\\ \\x(mi)=\frac{20km*1mi}{1.61 Km} \\x=12.42\ mi\\[/tex]

a. 12.4 mi

Have a fantastic day.
