If you don't learn, and improve, you are doomed to be as dumb as Trump.

MINEKRAFT XD is consuming too much of your time (addictively) and you run the risk of becoming a zombie.

Since 1 m = one thousandth of a kilometer, the 2 m/sec rate is 0.002 km/sec.

Replacing sec by 1/(60•60) gives 7.2 km/hr.
