A and B two cars respectively travel from ab at the same time. A's speed is 3 / 5 of B's. The two cars meet at 24 kilometers from the midpoint. How many kilometers is the distance between AB and a emergency
1 ÷ (3 / 5 + 1) = 3 / 8, so when we meet, a takes 3 / 8 of the whole journey
(1 / 2-3 / 8) = 1 / 8 the distance between the meeting place and the midpoint accounts for 1 / 8 of the whole journey
24 ÷ (1 / 8) = 192 km
So AB is 192 kilometers away
The speed ratio of the two vehicles is known to be 5:7, and the meeting place is 30km away from the midpoint
The distance when we met was 5:7
When they met, the bus made a full journey
5 ÷ (5 + 7) = 5 / 12
The distance between the two places
30 (1 / 2-5 / 12) = 360 km
Your praise is my motivation

A. The speed of car B is 4 / 5 of that of car a. the two cars Li meet at the distance of 30km
How many kilometers are there between a and B?
A: 30x2 = 60km
A: B speed = 5:4
The distance ratio is 5:4
A: 5 / (4 + 5) = 5 / 9
B go 4 / 9
The whole journey is 60 △ 5 / 9-4 / 9 = 60 △ 1 / 9 = 540km
