A and B start from ab at the same time and travel in opposite directions. A travels 50 kilometers per hour and B 40 kilometers per hour. A reaches the midpoint one hour earlier than B, and the two meet after a few hours
Distance 1 / 2 (1 / 40-1 / 50)
=2÷1/200
=400 km
Meeting time 400 ^ (50 + 40)
=400÷90
=4 and 4 / 9 hours

A and B start from ab at the same time and travel in opposite directions. A travels 50 kilometers per hour and B 40 kilometers per hour. A arrives at the terminal one hour earlier than B, and a travels 40 kilometers per hour
How many hours does line a arrive at the terminal?

Hello
Time ratio of Party A and Party B 40:50 = 4:5
A line 1 ÷ (5-4) X4 = 4 hours

A and B vehicles leave from ab respectively. A vehicle travels 50 kilometers per hour, B vehicle 40 kilometers per hour. According to different conditions, how many kilometers is the distance between AB and ab
1. After 3.5 hours, the two cars are still 45 kilometers apart. 2. After 4.5 hours, the two cars first meet and then 45 kilometers apart

（50+40）*3.5+45=360km
（50+40）*4.5-45=360km

The speed of car a is 50 km / h, and that of car B is 40 km / h,
When car a passes more than 50 km away from a and B, it meets car B. how many km are there between a and B?

What's the speed ratio
A: B = 50:40 = 5:4
What's the distance ratio
A: B = 5:4
When we met, a went
5÷（5＋4）＝5/9
A. B distance between the two places
50 (5 / 9-1 / 3) = 225 km
