A and B two cars from two places to each other, a car 56km per hour has 48km per hour, two cars meet at 32km from the midpoint. How many km is the distance between the two places?
A walks 56-48 kilometers more than B per hour = 8 kilometers
When they met, they were 32 kilometers away from the midpoint, which means that a walked more than half of the whole journey by 32 kilometers, and B walked less than half of the whole journey by 32 kilometers, so a walked 32 + 32 = 64 kilometers more than B
64 / 8 = 8 hours when meeting
The distance between the two places is 8 * (56 + 48) = 832km
A and B vehicles run from AB to each other, with a speed of 56km / h and B speed of 48km / h, and 424km in both places. If a walks for two hours, B will leave a few days after B starts
Meet? (equation)
Suppose that the two cars meet in X hours after B sets out
56（X+2）+48X=424
104X+112=424
104X=312
X=3
Car a and car B run from a and B at the same time. Car a runs 56 kilometers per hour and car B runs 48 kilometers per hour. The two cars meet at 32 kilometers from the midpoint. How many kilometers is the distance between a and B?
A: the distance between a and B is 832 km

- 3. The two cars leave from two places at the same time and meet each other in three hours. The speed ratio of car a and car B is 5:4, and the distance between the two places is 270km
- 4. A and B leave AB at the same time and meet at 2 o'clock. After meeting, the two cars continue to move forward. When a arrives at B, B is 60km away from A. It is known that the speed of a car is a car A and B leave AB at the same time and meet at 2 o'clock. After meeting, the two vehicles continue to move forward. When a arrives at B, B is 60km away from A. It is known that the speed of B is 2 / 3 of that of a, so find the distance between AB and B! With the sixth grade knowledge, this is from the math paper
- 5. Party A and Party B start from two places 60 kilometers apart and walk in opposite directions at the same time. The walking speed of Party A is 5 km / h, and Party B meets each other after riding for 3 hours to find the speed of Party B. If two people walk in the same direction from two places at the same time, Party A is in the front and Party B is in the back, how many hours will it take Party B to catch up with Party A? The answer is that B's speed is 15 km / h, and it takes 6 hours for B to catch up with a Please use the equation
