The distance between station a and station B is 480 km. A slow train starts from station a, 80 km per hour, and an express train starts from station B, 120 km per hour, After how many hours, the two cars are 600 kilometers apart
It takes (600-480) / (80 + 120) = 0.6 hours for two vehicles to drive in the opposite direction
It takes (600 + 480) / (80 + 120) = 9 hours for two vehicles to drive in opposite directions
It takes (600-480) / (120-80) = 3 hours to drive in the same direction when the express is ahead
When driving in the same direction and slow train ahead, it takes (600 + 480) / (120-80) = 27 hours
The distance between station a and station B is 1200 km. A slow train departs from station a, traveling 80 km per hour. An express train departs from station B, traveling 120 km per hour
The distance between station a and station B is 1200 km. A slow train departs from station a, traveling 80 km per hour, and an express train departs from station B, traveling 120 km per hour. The two trains start at the same time and face each other. How many km is the distance between the slow train and the midpoint when they meet? Let's set the time for meeting as t hours, and the distance between the slow train and the midpoint when they meet as X kilometers, that is, x = 1200 / 2-80t (thousand

They drove at a constant speed along the same route. After three hours of departure, they met. It is known that Party B traveled 90 meters more than party a when they met again. After one hour of meeting, Party B arrived at place A. they asked what the speed of Party A and Party B was and how to solve the equation
- 7. The distance between a and B is 60 kilometers. A and B ride bicycles from a and B to each other. If a starts half an hour earlier than B, B travels 2000 more per hour than a M. then when they meet, the distance they travel is exactly the same. Find the speed of a and B. don't use fractions, just make a binary linear equation system
- 8. Party A and Party B ride from a and B to each other. It is known that the speed ratio of Party A and Party B is 2:3.

- 9. The speed of a is 12 kilometers per hour, the speed of B is 15 kilometers per hour, and the speed of a is middle
- 10. Two hours later, they are 36 kilometers apart, and two hours later, they are still 36 kilometers apart Note: it's a system of linear equations with two variables!
- 11. A and B start from city a, C start from city B, a drive 40km per hour, B drive 45km per hour, C drive 50km per hour. If three cars are facing each other at the same time, C can only meet a car 10 minutes after meeting B. find the distance between two cities. (use one yuan linear equation solution)
- 12. If car a and B leave from a and B at the same time and go in opposite directions, they can meet on the way after 4 hours. It is known that the speed ratio of car a and B is 5:6. At this speed, if the two cars want to meet at the midpoint of a and B, how many hours should car B delay their departure?
- 13. A and B drive from a to B at the same time. A travels 40km per hour, B 35km per hour. A has a rest for 3 hours, B didn't stop all the time. As a result, a arrived one hour earlier than B. what's the distance between the two places?
