Shawnee Powell both run on the same track each morning. The ratio of the number of miles John runs to the number of miles power runs is 5:8.

Answer 1

Let the number of miles John runs be 5x
Let the number of miles Powell runs be 8x
Their total distance every morning is 5x + 8x = <<5x+8x=13x>>13x
The ratio of the number of miles John runs to the total distance is 5x/13x = 5/13. Answer: \boxed{\frac{5}{13}}.
