The original plan was to travel 80 kilometers per hour, but actually 20 kilometers more than the original plan How many meters is the distance between a and B?
Suppose it takes x hours for a car to go from place a to place B; then
80X=(x-2)100
X=10
10 * 80 = 800 (km) = 800000 M
The distance between a and B is 330 km. A truck runs 70 km per hour from a to B, and a bus runs 60 km per hour from B to a
Next: Mi, the truck will go ahead for an hour. When will the two cars meet again?
（330-70）÷（70+60）
=260÷130
=2 (hours)
A: one hour ahead of the freight train. Two hours later, the two cars meet
From place a to place B, it takes 8 hours for trucks and 10 hours for passenger cars. Two cars drive from place a to place B at the same time, and the trucks return immediately after arriving at place B
When the two cars meet, how many parts of the whole journey did the bus take? Life and death are at stake! Don't solve the equation!
2/(1+8/10)*8/10=8/9
The distance between a and B is several kilometers. It takes 6 hours for a bus to go from a to B, 4 hours for a truck to go from B to a, and% B for passenger and freight
A and B are several kilometers apart. It takes six hours for a bus to go from a to B, and four hours for a truck to go from B to a. the two passenger and freight cars leave each other at the same time, and meet 20 kilometers away from the midpoint. How many kilometers is the distance between a and B?
Set a distance of X meters
The bus speed is x / 6
The speed of the truck is x / 4
The speed sum of the two cars is 5x / 12, the time to meet is 12 / 5 hours, the distance of the bus is 2x / 5, the distance of the truck is 3x / 5, and the distance difference between the two cars is x / 5
Party A and Party B meet 20 kilometers away from the destination. The distance difference between the two vehicles is 40 kilometers
So x / 5 = 40, x = 200
So a and B are 200 kilometers apart
The distance between a and B is 240 kilometers, and a bus takes two hours to travel 35 times. According to this calculation, how many hours will it take to complete the rest of the road? (answer in proportion)
240 × 35 = 144 km, assuming that the rest of the road will take x hours to complete, (240-144): x = 144:2, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 144x = 96 × 2, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 144x = 192, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 113; a: the rest of the way will take 113 hours

The distance between Party A and Party B is 240km, and a bus takes three fifths of the whole journey in two hours. According to this calculation, how many hours will it take to complete the rest of the journey?
Answer by proportion
The rest of the journey will take x hours
3/5∶﹙1－3/5﹚＝2∶x
3/5 x＝2×2/5
x＝4/3
