C. 24 miles.
Add the 8 miles from the left side of the triangle, plus the 6 miles from the bottom and then use Pythagorean theorem to solve the hypotenuse which would be sqrt( 8^2 + 6^2)= 10. So 8+6+10=24 miles
Answer:
S = v1 t1 = 7 t1 traveling downstream
S = v2 t2 = 5 t2 traveling upstream
7 t1 = 5 t2
7 (6 - t2) = 5 t2 since t1 + t2 = 6
42 - 7 t2 = 5 t2
t2 = 42 / 12 = 3.5 hrs so t1 = 2.5 hrs
S = 7 t1 = 7 * 2.5 = 17.5 mi
Also, S = 5 t2 = 5 * 3.5 = 17.5 mi
