A. B is 384km away from each other. Car a and B start from the same place at the same time, and run in opposite directions for 4 hours. The speed of car a and B is known A. B is 384 kilometers away from each other. A and B start from the same place at the same time and meet each other for 4 hours. It is known that the speed ratio of car a and car B is 7:5. How can car a and car B travel thousands of meters per hour?
384 △ 4 = 96 (km / h)
96 × 7 / (7 + 5) = 56 km / h
96 × 5 / (7 + 5) = 40 km / h
A and B drive from a and B for 8 hours at the same time. When they meet, a drives 384km, and it is known that B is 1 / 4 faster than A. how many kilometers are there between a and B? D% a and B drive from a and B at the same time, and meet after 8 hours. When they meet, a drives 384km, and it is known that B is one fourth faster than A. how many kilometers are there between a and B?
The distance between the two places is 864km. The calculated distance is 384 × (1 + 1 / 4) + 384 = 864km
