A and B ride along the 3600m loop, and B rides faster. If they drive in the same direction at the same time, they will meet in 8 minutes, and if they drive in the same direction at the same time, they will meet in 72 minutes. How many meters do A and B walk per minute?

Answer; 3600 ÷ 8 = 450m, then the sum of the speeds of Party A and Party B is 450m per minute.

3600 ÷ 72 = 50m, so the speed difference between Party A and Party B is 50m per minute.

(450+50) ÷ 2 = 250m

450-250 = 200m

A: A speed is 200 meters per minute, and B speed is 250 meters per minute.
