Douglas Stefanski's spectacularly sleek hovercraft glides down a track of 36m. It takes 13 him seconds to cross the finish line. What is Super-Stavri's speed?

I really don't understand what's behind this question at all,

but I can sure do the math:

Speed = (distance covered) / (time to cover the distance).

= (36 meters) / (13 seconds)

= (36/13) (meters/second)

= 2.7692 ... meters per second (rounded)

(about 6.2 miles per hour).
