Since 0.6 miles = 1 km
=> 1 mile = 1/0.6 KM
=> 2 miles = 2*1/0.6 = 20/6 = 10/3 KMs

Hence A.

Option A : 10/3

0.6 mile = 1 km
=> 2.0 mile = ? km
=> x = 2/0.6
= 10/3 km or 3.333 km

kudos :) :-D

Another way to look at this is 0.6 mile is 1 kilometer so 1.8 miles is 3 kilometers, hence the answer should be greater than 3 and there is just one answer choice greater than 3, i.e. A.
