The number of more miles he needs to run to complete the race is 19 miles.
<h3 /><h3>How to find distance in miles?</h3>
He has run 7 miles from point a to point b of a race.
The entire race from point a to point c is 26 miles.

let
x = the more miles he needs to run
Hence,
x = 26 - 7
x = 19 miles
Therefore, he needs to run 19 more miles to complete the race.
