It takes 12 o'clock for a bus and 15 o'clock for a freight car to go from place a to place B. the two cars are facing each other at the same time. When they meet, the bus runs 98 kilometers more than the freight car. What is the distance between a and B?
The speed of the passenger is x, and it takes y hours when they meet
The cargo speed is x * 12 / 15 = x * 4 / 5
xy-(x*4/5)y=98
(1/5)xy=98
xy=490
Distance between a and B = XY + (x * 4 / 5) y = (9 / 5) XY
=882
Passenger and freight cars leave from a and B at the same time. After the two cars meet in 6 hours, they drive for another 3 hours. The bus arrives at B, and the truck is 24 hours away from a
Is the truck 240 kilometers away from Jiadi?
