the answer for this question is 9 times...
1) the two kids cross the river (150pounds)
2)one kid returns(75 pounds)
3) an adult crosses the river (145pounds)
4) a kid returns (75pounds)
5)two kids cross the river (150pounds)
p/s: now we have an adult at the beginning point , the opposite side we have an adult and two kids
then,
6)a kid returns(75 pounds)
7)an adult crosses the river (145pounds)
8)the kid on the opposite returns (75pounds)
ps: now we have two adults on the opposite side and two kids on the beginning point together with the boat
9)final step, the two kids cross the river.
9 steps totally to bring them to the opposite side of the river

i got a total of 440 all together so...
that would be how many times 150 can go into 440...
So, I got a total of 450 when i times 3.
So the answer is 3 times.
2 kids= 150 all together. = Once
2 Adults= 290= Twice with 10 left over
:]]
Simple.
Thanks for the riddle, Have a great day!!

Nine (9) times:
Children are A + B, 75 lbs. each
Adults are C + D, 145 lbs. each
First trip, both children go across (A + B) from Side 1 to Side 2 = 150 lbs.
Second trip, child A brings boat back from Side 2 to Side 1 = 75 lbs.
Third trip, Adult C crosses over from Side 1 to Side 2 = 145 lbs.
Fourth trip, child B brings boat back from Side 2 to Side 1 = 75 lbs.
Fifth trip, child A + child B cross over from Side 1 to Side 2 = 150 lbs.
Sixth trip, child A brings boat back from Side 2 to Side 1 = 75 lbs.
Seventh trip, Adult D travels over from Side 1 to Side 2 = 145 lbs.
Eighth trip, child B brings boat back from Side 2 to Side 1 =75 lbs.
Ninth trip, child A and child B make final trip from Side 1 to Side 2 = 150 lbs.
