$2 1/2$ miles in half an hour and $12 1/2$ miles in $2 1/2$ hours

Explanation:

Malia runs 5 miles in 1 hour.

So, she must be running $5$ x $1/2$ miles in $1/2$ an hour.
that's $5$ x $1/2$ miles
$2 1/2$ miles

and also, she must be running $5$ x $2 1/2$ miles in $2 1/2$ hours
that's $5$ x $5/2$ miles
$=25/2$ miles
$=12 1/2$ miles :)

See below

Explanation:

Use the unitary method

Distance covered in 1 hour= 5 miles
Distance covered in $1/2$ hour= $5/2$
= 2.5 miles
Distance covered in 2 $1/2$ hours = $5*2 1/2$
= $5*5/2$
= $25/2$
= 12.5 miles
