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