Six people are planning a five day backpacking trip. The trail they will take is 67 miles long. Everyone 12 and older will carry a 40- pound pack. Everyone younger will carry a 20-pound pack. What is the total weight (in pounds) of the groups backpack? The answer I got is 12 older 3x40=120. Everyone younger 3x20=60. 120+60=180. Is this right. This is what they want. (1) 140. (2) 160. (3). 180. (4). 200. (5). Not enough information is given.
