A speed skater competes in a race of 500 m. Their total time for completing the race is 42.5 s. The skater accelerates at a constant rate for the first 8 seconds and then maintains a constant speed for the rest of the race. Below is a sketch of the speed-time graph for the skater.
Work out the maximum speed of the speed skater during the race.
