About 2.5 miles

Explanation:

The exact conversion factor is:

1color(white)(.)"mile" = 1.609344color(white)(.)"km"

Since this is close to 1.6 = 8/5 we can reckon that:

4color(white)(.)"km" ~~ 5/8 * 4color(white)(.)"miles" = 2.5color(white)(.)"miles"

If the 4color(white)(.)"km" figure were accurate then the miles figure would be closer to:

4/1.609344 ~~ 2.4855color(white)(.)"miles"
