Dong Zhang and Wang Qiang ride bicycles along a circular road with a length of 1800 meters. If they go in opposite directions at the same time, they will meet again after 4 minutes. such as

The sum of their speeds is: 1800÷4=450 (m/min),

Suppose the speed of Dong Zhang is x meters per minute, then the speed of Wang Qiang is 450-x meters per minute. According to the meaning of the question, we can get the equation:

36x-36(450-x)= 1800，

36x- 16200+36x= 1800，

72x= 18000，

x=250，

450-250=200 (m/min);

A: Dong Zhang runs 250 meters per minute and Wang Qiang runs 200 meters per minute.

So the answer is: 250; 200.
