A and B have a total length of 1620 km. Car a travels 70 km per hour, and car B 65 km per hour. They leave each other from a and B. how many hours later do they meet? Answer in two ways! ~O(∩_ ∩)O~
1620 ÷ (70 + 65) = 12 hours
A 12 hour meeting
Let the solution meet in X hours
70x+65x=1620
135x=1620
x=12
Car a and car B are facing each other from a and B. car a travels 70 kilometers per hour and car B 65 kilometers per hour. The two cars meet. It's 20 kilometers from the midpoint of the whole journey. How many kilometers is the whole journey
The meeting time was 25 kilometers from the midpoint, and car a walked 20 * 2 = 40 kilometers more than car B
40 / (70-65) = 8 hours
A. B distance between the two places
(70 + 65) * 8 = 1080km
The two cars start from a and B at the same time and travel in opposite directions. Car a travels 70 kilometers per hour, while car B travels 65 kilometers per hour. The distance between them is 25 kilometers
A. B how many kilometers are there between the two places?
When they met, it was 25 kilometers away from the midpoint, and car a walked 25 * 2 = 50 kilometers more than car B
50 / (70-65) = 10 hours
A. B distance between the two places
(70 + 65) * 10 = 1350 km
A and B start from ab at the same time and travel in opposite directions. Car a travels 70 kilometers per hour and car B 65 kilometers per hour. The point where the two cars meet is 20 kilometers away from the midpoint. How many kilometers is the distance between AB and B
Let's meet in X hours. According to the meaning of the question, we get 70x-67.5x = 20, and the solution is x = 8, that is, the distance between AD and ad is 135 × 8 = 1080km
