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)   .
