Yes, 1 mile = 1.609 km, but you did your math wrong. Start out with some 'mental math' to get a rough estimate. 1 km is a bit more than ½ mile. Round off 13790 to 14000, and take half of it to get 7000, and you know it has to be a bit more than that. Then do the math and see it it looks close enough. 1 kilometer = 0.62137119 mile. 100 km = 62.137119 miles. 1,000 km = 621.37119 miles. 10,000 km = 6213.7119 miles. 13790km x 0.62137119 miles per km = 8,568.7087 miles. (Actually your answer, 22188.11 miles, is 35,708.3 kilometers, is about two and a half times to much..) You can also just put 13790km in miles in google and it will come back with 13790 kilometers = 8568.70874 miles. .
