Ni usiku wa manane. Kuna vijana wanne; A,B,C na D, wanahitaji kuvuka daraja lenye uwezo wa kuvusha watu wasiozidi wawili kwa wakati mmoja. Wote wanne wanahitajika wawe ng'ambo ya daraja baada ya dakika 17.. Kila mmoja ana speed yake ya kuvuka daraja: A yupo very fast anawezavuka kwa 1 min. B kwa 2 mins. C kwa 5 mins. D kwa 10 mins. Kama wakienda wawili alie fast hawez kumuharakisha alie slow kwahiyo speed itakayotumika ni ya slow. Pia kila wavukapo lazma wawe na tochi(tochi ipo moja). Mfano: A na D wakienda watatumia 10 mins na D akarudisha tochi,10mins jumla 20mins na watakua wamefeli. Je watavukaje kwa 17mins?

A= 1
B= 2+1
C= 5+1
D= 10

3+6+10 = 19 mins

wasivuke na wachelewe wote! ngoma drooo
ukimwaga ugali namwaga unga.
mahesabu kaka najua ya pesa tu sio ya kuvusha daraja.

sasa kaka hii ndo nini?

mkuu...ni lazma watumie 19 minutes!!!

mnavuka wenye speed tu..uyo anaetembea kwa maringo achaneni nae...anaishi kwa msemo there is no hurry in africa

hapana tatizo watu wanapokuwa wanawavusha hawo wanajikaririsha kwamba lazma mtu atakayerudisha tochi awe kati ya wale wawili walioenda! Hebu jaribu vizuri tena bila kujiwekea mipaka kama hiyo kama vipi tumia vijiti au vkaratasi kwa mfano wa watu!

"Wote wanne wanahitajika wawe ng'ambo ya daraja" muonekano wa swali unaonesha initially wote wapo at same location and minimal time is 19 mins.. vinginevyo swali lako halijajitosheleza kimaelezo. Kwa assumption hiyo iwapo at least mmoja atakuwa at opposite direction ni lazima upate <=17 mins.

Narubongo · Sep 17, 2012

assume A yupo opposite na B, C, D na torch ipo kwa B, C, D
A= 1
B= 2
C= 5
D= 10

C&D + A + A&B
10+1+2= 13 mins

kumbuka wote wanatakiwa wavuke daraja kwa mujibu wa maelezo yako A hajavuka daraja

Kwa mujibu wa swali lako, hawawezi kuvuka chini ya dakika 17. Na only minimal time ni AD+A+AC+A+AB = 19 min.

A na B wanavuka 2 min
A anarudisha torch 1 min
C na D wanavuka 10 min
B anarudisha torch 2 min
A na B wanavuka 2 min
jumla 17 min

oooh sawa mkuu nisahau ku+1

assume A yupo opposite na B, C, D na torch ipo kwa B, C, D
A= 1
B= 2
C= 5
D= 10

C&D + A + A&B + A [C na D wanavuka kwa 10mins halafu wanampa torch A ambaye atavuka kwa kutumia 1min, atamchukua B na watavuka kwa 2mins then A atarudi nga'mbo ya pili]
10+1+2+1= 14 mins [jumla ya muda watatumia]

kaka hapo umenoa C na D watampaje tochi A,ambaye yupo ngambo nyingine bila mmoja wao kuchukua muda wake na kuvuka kumpeleke tochi huyo A. Fanya ufanyalo dakika hazwez kupungua 17!

safi sanaa kaka!

acha ubishi na kujifanya unajua. Kwani hivi nini;A na B wakivuka 2mins na A akarudisha tochi 1mins(sum 3mins) halafu C na D wakavuka 10mins na B akarudisha toch(sum 12mins) halafu A na B wakamalizia kwa 2 mins. 3 12 2=17

nimekubali soln ya simplemind 100% yupo right.. nilitafsiri swali vibaya
