The railway from a to B is 700 kilometers long. A train leaves from a to B at 5:30 p.m. on the first day. The average train runs 200 kilometers per hour. When is the train Waiting to get to B?
700 / 200 = 3.5 hours
5.5+3.5=9
Children, arrive at the second place at 9:00 a.m~
The railway between Party A and Party B is 850 km long. A passenger train and a train depart from the two places at the same time. The passenger train runs 92 km per hour and the train 78 km per hour
Mi, after a few hours, the two cars met on the way
850/（92+78）=5
Five hours
The distance between a and B is 402 kilometers. A train and a bus leave from a and B at the same time. The speed of the bus is known to be 40 kilometers per hour. The speed of the truck is 3 / 4 of that of the bus. How many hours after the two trains leave, do they meet?
The distance between the two places is 402 km, and the two trains leave at the same time; the speed of the bus is 40 km per hour, the speed of the truck is 3 / 4 of the bus, 40 x 3 / 4 = 30, the speed of the truck is 30 km per hour; the speed sum of the two trains is 40 + 30 = 70 km per hour; the meeting time is 402 / 70 = 5
The whole journey of a railway from a to B is SKM, and the running time of the train is ah; the whole journey of a highway from a to B is m times of that of the railway,
The whole running time of the car is BH, so how many times of the speed of the train is that of the car?
Train speed = s / A
Vehicle speed = MS / b
therefore
The speed of a train is s / a (MS / b) = B / (AM) times that of a car
