An angler hooks a trout and reels in his line at $4i\frac{n}{s}.$ Assume the tip of the fishing rod is $13$ ft above the water and directly above the angler, and the fish is pulled horizontally directly toward the angler $($see figure$).$ Find the horizontal speed of the fish when it is $24$ ft from the angler.

When the fish is $24$ ft from the angler, its horizontal speed is about

$($Round to two decimal places as needed.$)$
