The distance between a and B is 260 kilometers. The bus and the truck are going from a and B at the same time. They meet 95 meters away from B. after meeting, they continue to move forward. When the bus arrives at B, the truck immediately returns to A. how many meters away from a? I want similar questions, from simple to difficult
95×3-260
=285-260
=15 km
The distance between a and B is 260 kilometers. The passenger cars and freight cars run from a and B at the same time
The distance between a and B is 260 kilometers. The bus and the truck are going from a and B at the same time. They meet 95 meters away from B. after meeting, the two cars continue to move forward. When the bus arrives at B, the truck immediately returns to A. how many meters away from a? Please write down the journey!
Proportion problem:
Bus speed: truck speed = (260-95): 95 = 33:19
Suppose two cars meet for the second time, X km away from Jiadi
(2×260－x):(260＋x)=33：19
8580＋33x＝9880－19x
52x＝1300
x＝25
The two cars met again at a distance of 25 kilometers
The distance between a and B is 260 km. The passenger cars and freight cars meet at 95 km
After meeting, the two cars continued to move forward. When the bus arrived at land B, and the truck arrived at land a, they all returned immediately?
Suppose that the speed of passenger cars is a and that of freight cars is B, then from the first encounter: (260-95) / a = 95 / B95a = 165ba = 33 / 19b, and from the second encounter, two cars are x kilometers away from Jiadi, then: (2 * 260-x) / a = (260 + x) / b (260 + x) a = (2 * 260-x) B, and substituting a = 33 / 19b into: (260
At the same time, the passenger car and the freight car leave from a and B. the passenger car travels 95 kilometers per hour, and the freight car 83 kilometers per hour. The two cars meet at 24 kilometers from the midpoint,
How many kilometers are there between a and B?
Come on, it's tonight
Meeting time:
24x2÷(95-83)
=48÷12
=4 (hours)
Distance between the two places:
4x(95+83)
=4x178
=712 (km)
