(A) 10/3
(B) 3
(C) 6/5

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

1 km 0.6 mile
X 2 mile

so cross multiply we get

2=0.6X

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.

1km = .6mi = 6/10mi

(10)1km = 6/10mi(10)
10km = 6mi

10/3km = 6/3mi
10/3km = 2mi

Question: 63

Difficulty: 550


Solution:

To solve, we must convert 2 miles to kilometers. We are given that 1 kilometer = 0.6 mile. Thus, we can convert 2 miles to kilometers.

2 miles x (1 kilometer)/(0.6 mile)

Notice that we put the unit "mile" in the denominator of our unit conversion ratio so that it will cancel out with "miles" in the numerator, and we will be left with kilometers.

2/0.6 kilometers

We can multiply the entire fraction by 10/10 to get rid of the decimal and we are left with:

20/6 = 10/3 kilometers

The answer is A.

Let's use equivalent ratios...

We'll compare ratios in the form kilometers/miles

If 1 kilometer is approximately 0.6 miles, which of the following best approximates the number of kilometers in 2 miles?
Let x = the number of kilometers that are equal to 2 miles

We can write the equation: 1/0.6 = x/2
Cross multiply to get: (1)(2) = (0.6)(x)
Simplify: 2 = 0.6x
Rewrite 0.6 as a fraction to get: 2 = (3/5)x
Multiply both sides by 5/3 to get: (5/3)(2) = (5/3)(3/5)x
Simplify: 10/3 = x

Answer: A

I think it's easier if you just imagine or draw a graphical representation of the problem. Just draw a line representing the 2 miles and then approximately mark 0.6 miles (1 km) a few times along the line - it will become clear that the solution is 2/0.6.
