Since x axis shows the distance and y axis shows the time, hence lower graph will show faster athlete and higher graph will show slower athlete. Height of A's graph is the lowest, hence, the race was won by A. Height of B's graph is lower than A's graph up to 25 km, hence B was running faster than A up to 25 km. The height of C's graph is the lowest from the beginning, hence he run very fastly from the beginning, Hence statement 3 is not correct.
