the speed is 80 m/h you find it by dividing the distance by time
AL2006

What you need is a definition of average speed.  Here it is:

     Average speed = (distance covered) / (time to cover the distance) .

For the race car in the question:

            Average speed = (200 mile) / (2.5 hour)

                                     = (200 / 2.5)  (mile/hour)

                                     =        80  miles per hour .

That doesn't seem all that fast for a race-car.
But the math is bullet-proof.
