☁ Four members of a band ☁

Four members of a band are walking to a night concert. They decide to take a shortcut, but must 交叉, 十字架 a bridge. Luckily they have one flashlight. Because of the varying size of their instruments, it takes each member a different amount of time to 交叉, 十字架 the bridge - it takes the first person one minute, the 秒 person two minutes, the third person five 分钟 and the fourth person ten minutes. They must 交叉, 十字架 the bridge in pairs, travelling at the slower speed so if the one 分钟 person went with the ten 分钟 person, it would take a total of ten minutes. Since there is only one flashlight, one person must come back across the bridge, then another pair can cross. They only have 17 分钟 to 交叉, 十字架 the bridge and still get to the 音乐会 on time. What order should they 交叉, 十字架 to get everyone across and get to the concert?
