Party A and Party B set out from two places at the same time, facing each other, and met 40 meters away from the midpoint. It is known that Party A traveled 11 / 20 of the whole journey, and how many kilometers did Party B travel when they met

40÷（11/20-1/2）×（1-11/20）
＝40÷1/20×9/20
＝800×9/20
= 360 km

11. Party A and Party B are traveling from two places at the same time, and they meet 40 meters away from the midpoint. It is known that Party A has traveled 55% of the whole journey. How many kilometers has Party A traveled?
