59.65 minutes

Explanation:

In order to solve this we first have to convert the velocity that she can run into kilometers, we know that a mile is equal to 1,609 kilometers, so we just have to multiply:

$\frac{1mile}{1.609 kilometers}=\frac{6.5 miles}{x} \\\x=frac{6.5*1.609}{1} \\x=10.46 lometers/hour$

So we know that she runs 10,46 kilometers in 60 minutes or one hour now we just have to divide the kilometers that she wants to run by the velicity she can run:

$Time=\frac{distance}{velocity} \\Time=\frac{10.4}{10.46} \\Time= 59.65$

She would take 59.65 minutes to run 10.4 kilometers.
