☁ Four members of a band ☁
Four members of a band are walking to a night concert. They decide to take a shortcut, but must attraversare, croce 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 attraversare, croce the bridge - it takes the first person one minute, the secondo person two minutes, the third person five minuti and the fourth person ten minutes. They must attraversare, croce the bridge in pairs, travelling at the slower speed so if the one minuto person went with the ten minuto 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 minuti to attraversare, croce the bridge and still get to the concerto on time. What order should they attraversare, croce to get everyone across and get to the concert?
