The speed ratio of car a and car B is 5:8. The two cars start from a and B at the same time and meet at 24 kilometers away from the midpoint. How many kilometers are there between the two places? [hint: when a and B meet, the distance ratio and speed ratio are the same]. When the driving time is the same, the distance ratio remains unchanged, and the speed ratio is the same
A: the distance between the two places is 208 km
The speed ratio of car a and car B is 5:8. The two cars leave from a and B at the same time. At the distance of 12 km from the midpoint, the two cars meet. How many km is the distance between the two cars?
We need to speak out the truth
Why 24km more?
The two cars leave from a and B at the same time and meet at 12 km from the midpoint
When meeting, car B travels more than car a: 12 × 2 = 24 km
Because the speed ratio of a and B is 5 to 8
Then B is better than a: 8-5 = 3
The whole course is: 5 + 8 = 13
So the whole journey is: 24 △ 3 × 13 = 104 km
A. B is 750 kilometers apart. A and B start from a and B at the same time. After five hours, they meet. The speed ratio of a and B is 7:8
What's the speed of car a and car B?
750/5=150
A: 150 * 7 / 15 = 70
Already: 150-70 = 80
A and B set out from a and B, and after 8 hours, they met 44 kilometers away from the midpoint to find out that the speed ratio of a and B is 5:4. How many kilometers is the distance between a and B
When we meet,
44 × 2 = 88 M
The distance ratio is equal to the speed ratio, which is 5:4
AB distance: 88 ÷ (5-4) × (5 + 4) = 792m
