The distance between a and B is 800 kilometers. The two cars are facing each other. The speed ratio of a and B is 6:5. When they meet, how many kilometers do the two cars walk? Detailed, quick!
Method 1: the travel ratio when meeting is: 6:5, that is, line a: 6 / 11, line B: 5 / 11, that is, line a: 800 * 6 / 11 = 4800 / 11km; line B: 800 * 5 / 11 = 4000 / 11km. Method 2: if line a has x, line B has 800-xx: (800-x) = 6:5x = 4800 / 11b: 800-4800 / 11 = 4000 / 11method 3: a
The distance between a and B is 800 kilometers. AB and ab cars are facing each other from the two places. It is known that the speed ratio of AB car is 6:5. How many kilometers did the two cars travel when they met
A 800 × 6 / (6 + 5) = 4800 / 11km
B 800 × 5 / (5 + 6) = 4000 / 11km
A 800 △ (6 + 5) × 6 = 4800 / 11km
B 800 △ (6 + 5) × 5 = 4000 / 11km
A 800 (1 + 5 / 6) = 4800 / 11km
B 4800 / 11 × 5 / 6 = 4000 / 11km
