One day, Lele bought a new toy dog and a toy cat. It is known that the toy dog and the toy cat start from both ends of the living room at the same time and walk towards each other. When the toy dog reaches the opposite side, the toy cat still has 2 meters to reach the opposite side. , if the speed of the toy dog is 50 cm per minute, and the speed of the toy cat is 30 cm per minute, how many meters are there between the two ends of the living room?
一天乐乐新买了一只玩具狗和一只玩具猫，已知玩具狗和玩具猫同时从客厅两端出发，相向而行，当玩具狗到达对面时，玩具猫还有2米才能到达对面，若玩具狗速度每分钟50厘米，玩具猫速度为每分钟30厘米，那么客厅两端相距多少米？
