Use the relationship between distance (d), time (t) and speed (v), d = vt to repeat the calculation we did in class, but this time using the English units. Use the fact that GEO satellites orbit at 22,236 miles above Earth's equator, and that the speed of light is 1.86 x 105 mi/s. (Note that both of these values are equivalent to those used in class.)
