Question

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?

Answer 1

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) .
