On the same road, a and B start at the same time from a and B, 900 meters apart. A travels 200 meters per minute and B 250 meters per minute How long does it take for them to be 2700 meters apart

On the same road, a and B start at the same time from a and B, 900 meters apart. A travels 200 meters per minute and B 250 meters per minute How long does it take for them to be 2700 meters apart

(2700-900)/(250-200)=1600/50=32
In the same direction

On the same road, Xiao Wang and Xiao Ming start at the same time from AB, which is 900 meters away. Xiao Wang is 200 meters / min and Xiao Ming is 250 meters / min. how long is the distance between them 3700 meters?
To calculate the process. Same direction
