Miles per second is just a fraction.

(186,000 miles / 1 second) + (93,000 miles / 1 second) = 279000 miles / 1
second

How much distance traveled with the one second 279,000 miles.
You have completely forgotten how to add miles I see?

Fine as far as it goes. One could, for instance, shoot a light beam from
point A and a pellet going 0.5c from point B and calculate closing
velocity as 1.5 c.

However, the pellet will observe the light beam going towards it at
lightspeed.

Actually, Newtonia can explain the "rubber ruler" effect along with the
"taffy ticker". but of course you refuse to think about any such
explanations.

Newtonia can't explain why a 7 TeV proton isn't going many times
lightspeed.

We have been through this too many times. Blowing "more wind" at a
sailboat does not make it travel faster. The sailboat only has a certain
size sail.

Please, Mr Math man calculate the energy in a 1 mile wide by 1/4 mile
high wind with a length of 10 meters. How fast should a 1 ton boat move
with all that energy hitting it at 60 mph?

Did you want to discuss sailboats, spacetime, or particle physics? But OK.

First, there's several issues here; the units are English. Also, a modern
sailboat can generate sideways force since its sail is *curved*, acting in
a manner similar to an airplane's wing. The keel also plays a role in
this sailing.

There's also drag.

But of course you're being slightly silly anyway. A 1 ton, 1 ounce, or 1
pound keelless boat will move at 60 mph -- the same as the windspeed -- if
one neglects friction. Since it's a 1 ton boat one gets a kinetic energy
of approximately 392,000 J. (A keeled boat's speed will be
direction-dependent.)

As for the amount of energy in a rectangular parallelpiped 1 mile by 1/4
mile by 10 meters at 60 mph -- that's a good question, and the answer I
get would be temperature-dependent (ideal-gas law), though the variance
wouldn't be all that much.

Assuming 40 moles per cubic meter, I get 6,500,000 m^3, 2.59 * 10^8 moles,
7.51 * 10^6 kg, 2.70 * 10^9 J -- with only a tiny fraction interceptable
by the sailboat, of course.

It's still legal to go .sigless.
