Xiaohong and Xiaoqiang start from home at the same time. Xiaohong walks 52 meters per minute and Xiaoqiang 70 meters per minute. They meet at a on the way. If Xiaohong starts 4 minutes ahead of schedule and Xiaoqiang walks 90 meters per minute, they still meet at a. how many meters are Xiaohong and Xiaoqiang's homes apart?

Xiaohong and Xiaoqiang start from home at the same time. Xiaohong walks 52 meters per minute and Xiaoqiang 70 meters per minute. They meet at a on the way. If Xiaohong starts 4 minutes ahead of schedule and Xiaoqiang walks 90 meters per minute, they still meet at a. how many meters are Xiaohong and Xiaoqiang's homes apart?

Originally, the speed ratio of Xiaohong and Xiaoqiang was 52:70 = 26:35, then Xiaoqiang walked the whole course of 3561 when they met; later, the speed ratio of Xiaohong and Xiaoqiang was 52:90 = 26:45, when they met, Xiaoqiang also walked the whole course of 3561, then Xiaohong walked the whole course of 3561 × 2645 × = 18 after Xiaoqiang started

Xiao Ming and Xiao Li are walking towards each other. Xiao Ming is 52 meters per minute and Xiao Li is 70 meters per minute. They meet at a on the way. If Xiao Ming starts 4 minutes ahead of time, they can get there quickly
The degree remains the same. Xiaoli's clock is 90 meters in each branch. They still meet at a. how many meters is the distance between Xiaoming's and Xiaoli's homes?

Xiaoming and Xiaoli's homes are x meters apart, 52X / (52 + 70) = 52 × 4 + 52 (X-52 × 4) / 52 + 90
X = 2196 Xiaoming and Xiaoli's homes are 2196 meters apart

Xiao Ming and Xiao Li walk from 960 meters apart. Xiao Li walks 58 meters every minute, Xiao Ming walks 62 meters every minute? (solution of a series of equations)

Let two people meet after X minutes & nbsp; 58x + 62x = 960 & nbsp; & nbsp; & nbsp; & nbsp; 120x = 960120x △ 120 = 960120 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 8 a: two people meet after 8 minutes
