Yes. Because miles and kilometers are units of distance measurements. They have a fixed ratio, hence, there will always be a constant linear relationship between them. Or a constant slope. One mile is approximately 1.61 kilometers. So, just multiply any measurement of mile with 1.61 to get the distance in km.
You add all of the numbers up each row and divide by how many there are so: row one: if u add it all up it would be 10 then divide by how many there are
