Question

If 1 kilometer is approximately 0.6 mile, which of the following best approximates the number of kilometers in 2 miles?

a) 1.2 kilometers
b) 2 kilometers
c) 3 kilometers
d) 4 kilometers

Answer 1

The best approximation for the number of kilometers in 2 miles, given that 1 kilometer is approximately 0.6 mile, is 3 kilometers (c).

Step-by-step explanation:

If 1 kilometer is approximately 0.6 mile, we can set up a proportion to find the number of kilometers in 2 miles. Since we have the conversion factor, we can write:

1 km = 0.6 mile
x km = 2 miles

To find 'x', we can solve for it as follows:

x km = (2 miles) / (0.6 miles per km)
x = 2 / 0.6
x = 3.33...

The closest approximation to 3.33 kilometers is 3 kilometers (c). Hence, the best approximation for the number of kilometers in 2 miles is 3 kilometers.
