16:50 he doesn't know the difference of miles vs kilometers. Simple math though. 1° of latitude = 60 Nautical miles . Earth is 365° around. Then convert from nautical to Miles. His math is how we get what crashed the Mars satilite . And you can't do the math with longitude because it's different thicknesses. Fatter at the equator, due to the Earth spinning so fast.
