He plans to go for a very long hike.  He knows that he can get 1 resupply during the hike that will be 25% as large as his first pack.  He can hike at a rate of 2.5 mph.  He is going to hike 8 hours a day for 5 days.  How much does he need to bring with his first pack?
conversations.from: assistant
conversations.value: He is going to hike 8*=40 hours
  That means he will be hiking for 40*2.5=100 miles
  So he needs 100*.5=50 pounds of supplies
  With the resupply he can get up to 1+.25=1.25 times his initial pack
  That means his initial pack has to weigh 50/1.25=40 pounds
