Party A and Party B are facing each other from ab. it is known that the speed of Party A and Party B is 2:3, and Party A walks 15 minutes earlier than Party B. after 1 hour and 45 minutes, they meet, and Party A walks 6 kilometers less than Party B Ask a and B about their cycling speed and the distance between a and B (the process should be detailed)

Party A and Party B are facing each other from ab. it is known that the speed of Party A and Party B is 2:3, and Party A walks 15 minutes earlier than Party B. after 1 hour and 45 minutes, they meet, and Party A walks 6 kilometers less than Party B Ask a and B about their cycling speed and the distance between a and B (the process should be detailed)

1 hour 45 minutes = 105 minutes
6 km = 6000 m
6000÷【3×105-2×（105-15）】
About 44 (m)
Speed of a = 2 × 44 = 88 (M / min)
Velocity of B = 3 × 44 = 132 (M / min)
Distance = 88 × (105-15) + 132 × 105 = 21780 (m)

Party A and Party B go from AB to ab. in 3, Party A goes 15 minutes earlier than Party B. in 1 hour and 45 minutes, Party A meets Party B. Party A walks 6 kilometers less than Party B. speed and distance between two places

Let the velocity of a be x, then the velocity of B be 3x / 2
A total of 1.75 hours, B a total of 1.5 hours
1.5x*1.5-1.75x=6
x=12,3x/2=18
A walked 1.75 * x = 21 km
B walked 2.25 * 12 = 27 km
The distance between the two places is 48 km

Party A and Party B are traveling from two places at the same time. After 4 hours, they meet at a distance of 4 kilometers from the midpoint. A is faster than B. how many kilometers is a faster than B per hour?

A: A is 2 kilometers faster than B per hour

Party A and Party B are traveling from two places at the same time, and they meet 40 meters away from the destination. It is known that Party A has traveled 11 / 20 of the whole journey. How many meters has Party A traveled?

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