When running a 100 meter race matt reaches his maximum speed when he is 40 meters from the starting line, and 7 seconds have elapsed since the start of the race. Matt continues at this max speed for the rest of the race and is 80 meters from the starting line 12 seconds after the start of the race. What is max's max speed?

80 - 40 =40 meters - distance where Max is running at maximum speed.
12 - 7 = 5 seconds - it took him to run the above distance  at maximum speed.
40 / 5 = 8 m/s - Max maximum speed.
