By the wording and possible answers I think a trip is a oneway crossing of the river. Does this help? Janice wrote back Penny, Janice, I think 17 is a possible answer but 33 is also. Wesley has to cross the river 17 times with grain but he has to return to get more grain 16 times for a total of 17 + 16 = 33 trips. Penny
