A and B are going from AB to ab at the same time. A arrives at the destination in 3 hours, and B is 20 kilometers away from the destination. It is known that the speed ratio of a and B is 3:2 to find the distance between the two places

A and B are going from AB to ab at the same time. A arrives at the destination in 3 hours, and B is 20 kilometers away from the destination. It is known that the speed ratio of a and B is 3:2 to find the distance between the two places

If the velocity of a is 3x, then the velocity of B is 2x
So the distance between the two places is 9x
So 3 times 3x = 3 times 2x + 20
That is 9x = 6x + 20
So 3x = 20
So the distance between the two places is 60 kilometers
If you don't understand, you can ask,

Four hours after a and B start from point AB at the same time, car a reaches the midpoint and car B is 50 kilometers away from Zhongdan. It is known that the speed ratio of a and B is 4:3
Find the distance between a and B

When car a reaches the midpoint, car B runs the whole journey
1 / 2 △ 4 × 3 = 3 / 8
What is the distance between the two places
50 (1 / 2-3 / 8) = 400 (km)

The speed of car a is 70 kilometers per hour, and that of car B is 50 kilometers per hour,
When car a passes more than 60 km away from AB, it meets car B. find the distance between AB and ab

Let the distance be X
(x/3+60)/70=[1-(x/3+60)]/50
=> 50x/3+3000=140x/3-4200
=> 7200=30x
=>X = 240 km
Distance 240 km

The speed of car a is 50 kilometers per hour, and that of car B is 40 kilometers per hour,
The two cars meet when they pass more than 50 km away from ab. find the distance between AB and ab
. quick tat

Speed ratio: A: B = 50:40 = 5:4
5 / (5 + 4) = 5 / 9
AB distance between two places: 50 ÷ (5 / 9-1 / 3) = 225 (km)
