Xiao Li, Xiao Ming is practicing running on the 400 meter circular track, Xiao Li 1. Run 220 meters per minute, Xiao Ming run 280 meters per minute. They run from the same starting point at the same time and meet each other for the first time in a few minutes? If they run in the same direction, they meet each other for the first time in a few minutes 2 if the solution of the equations 3x + y = 2K, 2y-x = 3 satisfies x1, find the integer solution of K The sum of the values of X and Y satisfying the equations 3x + 5Y = m + 2,2x + 3Y = m is equal to 2, and the value of m2-2m + 1 can be obtained Xiao Li and Xiao Ming practice running on the 400 meter circular track. Xiao Li runs 220 meters per minute and Xiao Ming runs 280 meters per minute. They run in reverse from the same starting point at the same time. They meet for the first time in a few minutes? If it's running in the same direction, the first meeting in a few minutes? Solution of a series of equations

Solution 1: suppose two people run from the same starting point in the opposite direction at the same time and meet for the first time in X minutes. According to the meaning of the question, the equation can be formulated as follows: 220x + 280x = 400500x = 400X = 0.8 two people run from the same starting point in the opposite direction at the same time and meet for the first time in 0.8 minutes
