Party A and Party B set out from both places of AB at the same time. If they set out at the same time, they will meet 24 minutes later. If Party B sets out 10 minutes earlier than Party A, they will meet each other, Party A and Party B set out from both places of AB at the same time and face each other. If they set out at the same time, they will meet 24 minutes later. If Party B sets out 10 minutes earlier than Party A, Party A will meet Party B 20 minutes later. How many minutes does it take for Party A to go to place B and Party B to go from place B to place a?

If it takes X minutes to set a, there are:
20/x+30×(1/24-1/x)=1;
10/x=6/24;
10/x=1/4;
x=40;
So it takes 40 minutes for a and 60 minutes for B;

The distance between a and B is 1200 meters; the two people set out from a and B at the same time,
When the gong and the Gong speed up 50 / 100 respectively, Party A and Party B start each other, how many times do they meet after they start


Speed up 50 / 100, that's 1 / 2
The speed is increased by 1 / 2, so the time is reduced by 1 / (2 + 1) = 1 / 3
10 * (1-1 / 3) = 20 / 3 minutes
So we'll meet in 20 / 3 minutes



A and B are in ab. if they walk in opposite directions, they will meet in 10 minutes. If they walk in the same direction, a will catch up with B in 35 minutes. It is known that B's speed is 80
M / min, the speed of A
We know B's speed is 80


Suppose: the speed of a is x m / min
(x-8)×35=10×(8+x)
45X=360
x=8



On a circular runway, a starts from point a and B starts from point B at the same time and goes in reverse. After 8 minutes, the two meet. After 6 minutes, a arrives at point B, and after 10 minutes, the two meet again. It takes a week for a circle______ Minutes


The speed ratio of Party A and Party B is: 8:6 = 4:3, 1 △ 1 (6 + 10) × 44 + 3, = 1 △ 116 × 47, = 1 △ 128, = 28 (minutes); a: it takes 28 points for a round trip
