(2016 Math League, Grade3）  Running Man is running a certain distance at a constant speed of $$300$$m/min and can finish the entire distance in $$3$$ hours. If he ran at a constant speed of $$360$$m/min, how many minutes less would it take him to run this distance?  Running Man是以$300$ m/min的恒定速度跑完一段距离，可以在$3$小时内跑完全程$$.$$ 如果以以$360$ m/min的恒定速度跑完这段距离会少花多少分钟? 
选项为:A:$$30$$  B:$$150$$  C:$$180$$  D:$$360$$  请回答其中一个选项.
