Xiaoli and Xiaomin practice running on the 400 meter circular track, and their speed ratio is 4:5. When they go out in the same direction at the same time, they go out in the same place The first time we met 8 minutes later, how many meters did Xiao Li and Xiao Min run each minute? Using the equation, the concrete solution


Let Xiaoli be 4xm / min, Xiaomin be 5xm / min
∵ 8*4x+400=8*5x
32x+400=40x
32x-40x=-400
-8x=-400
x=50
∴ 4x=4*50=200
5x=5*50=250
A: Xiaoli is 200m / min, Xiaomin is 250m / min
The mid-term exam is coming soon. I wish you a high score!



Xiao Li and Xiao Ming practice running on the circular track 400 meters apart. Xiao Li runs 220 meters per minute and Xiao Ming runs 280 meters per minute. They run from the same starting point at the same time. A few minutes later, Xiao Li and Xiao Ming meet for the first time?
