At last month's rehearsal, four top athletes competed in two qualifying 400 metre races. As the results were expected to be mislaid, various notes were taken to ensure the accuracy of the overall placings:
No-one finished both races in the same position. John beat Mr Donald in both races. Steve Curtail came third in the second race and Dave came last in the first race. In the second race, Mr Arnold won and Mr Bowler came last. In the first race, Steve beat Kev, but Kev beat John.
Can you determine who finished where in each of the races?
