Answer:

The answer is C. 688 km

Explanation:

you do is multiply the miles x 1.6 and you will get k. so 430miles x 1.6 = 688k

and 665miles x 1.6 = 1064k

1 Mile is 1,6 Kilometers

430 Miles = 688 Kilometers (430 * 1,6)

665 Miles = 1064 Kilometers (665 * 1,6)

1. if you want your questions answered, don't whine -- just ask the question. for example, in this you haven't really asked anyone the question. They have to assume what you are trying to find out.

2. It is simple math if you understand the equation you gave:

You are solving for "k" which is kilometers;

You have been given the distance which is "d" in miles (430 miles and 665 miles)

The equation means: "k" equals 1.6 times the value of "d"

so the answers to your implied questions are:

k = 430 x 1.6 = 688 kilometers

k = 665 x 1.6 = 1064 kilometers

You might also asking your question in a more appropriate category. this is more of a math problem than a geography question (the names of the cities is irrelevant to the answer; the relevant part is the distance in miles).

The number of kilometers is ALWAYS greater than the corresponding miles. For example 1 mile = 1.6 km, so there is no way that when you convert miles to kilometers you will ever come up with a lower number of kilometers than the miles.
