[quote="Avis"]Dan and Karen, who live 10 miles apart meet at a cafe that is directly north of Danâ€™s house and directly east of Karenâ€™s house. If the cafe is 2 miles closer to Danâ€™s house than to Karenâ€™s house, how many miles is the cafe from Karenâ€™s house?
use triangle rectangle 3-4-5
so equivalent 4-6-10
stupid mistake see correction below
