Party A and Party B set out from both places of AB at the same time and walked towards each other. The speed of Party B was 2 / 3 of that of Party A. after they met, they continued to move forward, A to B and B to a both return immediately. It is known that there is a distance of 2000 kilometers between the two places where they met. Find the distance between AB and B
Party A and Party B set out from two places of AB at the same time and walk in opposite directions. The speed of Party B is two-thirds of that of Party A. after they meet, they continue to move forward, and both Party A and Party B immediately return to place B and place A. It is known that the distance between two places of meeting is 2000 km, so the distance between two places of AB? 2000 △ [3 / (3 + 2) × 3-1-2 / (3 + 2)] = 2000 ^
A and B start from a and B at the same time, and walk towards each other. B's speed is 2 / 3 of a's. after two people meet, they continue to move forward, a to B and B to a
Analyze in detail, demand
They all returned immediately to know that the distance between the two places where they met was 3000 meters. For the distance between AB, the answer is 7500 meters, I'm a bit stupid. I don't understand. Quick search
It is known that the speed of B is 2 / 3 of that of A. We can get that the speed ratio of a and B is 3:2. When we meet for the first time, the distance between a and B is 3 / (3 + 2) = 3 / 5, and the distance between a and B is 3 / 5. When we meet for the second time, the distance between a and B is 3 / 5
B's speed is two-thirds of a's. A and B start from a and B at the same time. If they are going in opposite directions, they will meet in an hour. If they are going in the same direction, a needs to go
5 hours
B's speed is 23 times of a's. two people set out from a and B at the same time. If they walk in opposite directions for one hour, how many hours does it take a to catch up with B?
(2 + 3) / (3-2), = 5 / 1, = 5 (hours); a: if you go in the same direction, it takes 5 hours for a to catch up with B
