If 1 kilometer equals 0.6 miles, how many miles are in 3 kilometers?

• A. 1.8 miles
• B. 2.4 miles
• C. 1.2 miles
• D. 0.6 miles

Answer: (A)

When you know a conversion factor, distances scale by multiplication. Here, 1 kilometer corresponds to 0.6 miles, so 3 kilometers multiply by that same factor: 3 × 0.6 = 1.8. Therefore, 3 kilometers equals 1.8 miles. You can also see this by treating 0.6 as 3/5 and computing 3 × 3/5 = 9/5 = 1.8.
