$31.5$ $31.5$ miles.

Explanation:

We can use the formula:
$r t = d$ $rt=d$
where $r =$ $r=$ rate, $t =$ $t=$ time, and $d =$ $d=$ distance. We know $r$ $r$ and $t$ $t$ from the problem. $r = 2.25$ $r=2.25$ mi $/ 1$ $/1$ day and $t = 14$ $t=14$ days. Substituting and simplifying:
$r t = d$ $rt=d$
$2.25$ $2.25$ mi $/ 1$ $/1$ $cancel(day)$ $*$ 14 $cancel(days)$ $=d$
$2.25$ mi $*14=d$
$d=31.5$ mi
So at the end of 14 days, Tessa will have run $31.5$ miles.
