[Melinda G]

ok there was a man that had to sell his hay at the market across the river.he had his goats horses and hay.when he crossed the river he couldnt leave the horses or the goats with the hey or they will eat it. so how many trips did he do in all. prove your answer if you can! oh and he hada reall smal raft and could only carry him and 1 thing at a time. and find the least # of trips 5 horses 7 goats and a load of haythis answer is a #I'm not going to say who and what the answer was but someone got it right. keep guessing and check tomorrow to see who won!!!

 

[MelissaAnn]

he makes one trip he leaves the goats and horses behind and then sells the hay and comes back .. just taking a stab at it

 

[meli]

they can eat hay, not hey

 

[melbournewooferblue]

i agree with elle otherwise it is impossible at some point the hay will be left with an animal

 

[melissa]

NONE! he could just use the bridge next to the raft.

 

[Melba S]

this riddle is only possible with 2 animals and 1 hay. otherwise one trip,,,go across with the hay and sell it.

 

[Melanie_x]

arrrg i cant do it

 

[melina]

Go across with the hay, return. Go across with the goat, return with the hay. GO across with the horse, return. Then go across with the hay once more. SO 7 trips across the river in all.

 

[melcw592]

two trips: one to take the hay across, then he goes back, loads the goats, tethers all the horses together, and crosses the river the second time with the horses swimming behind the raft

 

[Melissa H]

The least number of trips is 1. He goes across with the hay and therefore the horses and goats can't eat it.

 

[Melchizedek]

ok 1st takes hay= 1trip, then takes 7 goats 1 at a time which is 14 trips (7 trips back and forth), then he takes 5 horses 1 at a time which is 10 trips (5 trips back and forth) so my answer is ------- 25 trips

 

[MelanieBeth]

umm 13? lol

 

[Melissa G]

I would say he sold the hay and came back...any other way they would have ate the hay...So in that case im guessing Elle was correct, unless he decided to make no trips at all 0...he didn't have anything to tie the horses and goats up to there for he decided he would come back when he wasn't with so many animals.

 

[melisa_estlack]

the least number of trips would be 1 because he just has to take the hay across and sell it.

 

[melfox]

He takes the hay to other side, sells them and comes back to take all the goat and horse to other side, it takes 13 time return trip across the river to complete his mission.
