The fastest train in the world moves at 300,000 km/s. how far will it go in three hours?

(300,000 km/s) x (3,600 sec/hr) x (3 hrs) = 3,240,000,000 km.

                                                                 (That's 3.24 x 10⁹ km.)

                       (That's to the moon and back about 4,230 times.)



The math above is bullet-proof and air-tight.
The reason for the whacky answer is the fact that
the fastest train in the world does not move at
anywhere near 300,000 km/sec.  That number
is the speed of light, for gosh sakes !
