The first time they met is 180km away from A. after meeting, they continue to move forward. They arrive at Ba and return along the same road. The second time they are 260km away from A. how many kilometers are there between AB and a?
(180*3+260)/2
=800/2
=400
A and B start from a and B at the same time. For the first time, they meet at a distance of 75 km from a and continue to move on. After arriving respectively, they return to B for the second time, and then they are 55 km away from B
Meet to seek the distance between ab!
Let's talk about ideas. Let's see what's going on
When they met for the first time, they traveled a total distance of AB, of which car a traveled 75 kilometers;
When the two vehicles meet for the second time, they travel three times of the distance between AB and a, and car a travels 75 × 3 = 225 km;
It is known that the second meeting was 55 kilometers away from B, that is, when a car passed AB, the distance between the two places was 55 kilometers more;
The distance between AB is 225-55 = 170 km
Car a and car B are facing each other from a and B at the same time. When they meet for the first time, car a is 70 kilometers away from a, and then they continue to move on,
At the end of the second meeting, car a is 20 kilometers away from B. how many kilometers are there between a and B?
Suppose that the distance is x km, the first encounter, a and B two cars go together for X km, and the second encounter, a and B two cars go together for 2x km, which shows that the time of the second encounter is twice that of the first encounter. The distance of a car in the first encounter is 70 km, the distance of a car in the second encounter is X-70 + 20 = x-50 km, then x-50 = 70 * 2, x = 190 km
Party A and Party B are facing each other from AB, and they first meet 180 meters away from a,
The second meeting is 200 meters away from ground A. how many meters are there? Don't use equation
How many meters is the distance between AB and ab?
180*3-200=340

- 1. The first time they met, they were 80 kilometers away from A. A and B. B. A and B. a returned immediately at the same speed -- dizzy, can't remember. Urgent Party A and Party B set out from ab at the same time, and they went opposite each other. The first encounter is 80 kilometers away from a, and a and B return at the same speed. The second encounter is 3 / 5 of the distance from B. how many kilometers is the distance between a and B? Help me. By 12:00
- 2. At the same time, the two cars are facing each other from station a and station B. for the first time, they meet 40 kilometers away from station A. then they go on to the station and return to meet 20 kilometers away from station B. find the distance
- 3. A. B two cars leave from station a and station B at the same time. For the first time, the two cars meet 32 kilometers away from station A. after meeting, the two cars continue to drive. After arriving at station B and station a respectively, they immediately return along the original road. For the second time, they meet 64 kilometers away from station A. so how many kilometers are there between station a and station B?
- 4. A and B start from a and B at the same time and run in opposite directions. For the first time, the two cars meet at 64 km away from B. after meeting, they continue to drive at the same speed and return to the opposite station. The two cars meet for the second time at 48 km away from a. what is the distance between the two meeting places?
- 5. The distance from city a to city B is 240 kilometers. When a truck goes there, it travels 60 kilometers per hour. When it returns by the same way, it travels 40 kilometers per hour The average speed of the truck to and from ab
- 6. Party A and Party B walk from the two cities of AB 580 meters apart. Party A walks 50 meters every minute, and Party B walks 70 meters every minute. Party A walks for 2 minutes before Party B starts B set out a few minutes later, the two met. How many meters from the midpoint of AB
- 7. A and B both walk from ab at the same time. A walks 100 meters per minute. The speed of a and B is 5:4. After 5 minutes, they walk 3 / 5 of the whole distance, which is longer than ab
- 8. A. B is 1000 meters apart. A and B set out from a and B at the same time and walk back and forth between a and B. if the first meeting is 100 meters away from the midpoint of a and B, how far is the second meeting place from the first meeting place?
- 9. AB is 10000 meters away from a, B rides a bike, B walks at the same time, the speed from a to B is 4 times faster than B, a delays for a period of time, B arrives at B, a has 200 meters, a delays time, B walks more
- 10. It's better to give 100 points 1. Party A and Party B set out from ab at the same time and walk towards each other. After meeting, Party A goes on to arrive at place B after 18 minutes, and Party B goes on to arrive at place a after 8 minutes. How many minutes do they meet after starting? 2. Car a and car B start from a and B respectively and run in opposite directions. When they start, the speed ratio of car a and car B is 5:4. When they meet, car a's speed decreases by 20%, and car B's speed increases by 20%. In this way, when car a arrives at place B, car B is still 10 kilometers away from place A. then, how many kilometers are there between car a and car B? 3. The car goes from a to B. if the car travels 20 kilometers less per hour than the original, it will take four fifths of the original time. If the car travels 20 kilometers more per hour, it will take 1.2 hours less than the original time. How many kilometers are there between a and B? It's better to use formula
