7. Peary set out onto the polar sea ice with 6 expedition members, 21 Eskimos, and the best 140 dogs (out of 246) with 19 sleds carrying loads of 450 to 500 lbs.
He formed them into 6 teams (divisions) and they broke the trail, established igloo camps, and carried out a system of one-way relays to move supplies forward, sending the injured and poorer performers back to land, one team at a time along the way to 88° N, while Peary saved his own energy for the final dash.

10,000 lbs of supplies (food, fuel, shelter…)
20 sleds that can carry 500lbs
140 dogs (7 per sled)
~500 miles to travel (inc. detours)
Each team has to have enough supplies to return….and the return gets longer for each of the later support teams…
Assume 5 teams of 4 sleds (100 miles for team 1, 200 for team 2…etc). What is the total distance travelled?
How much food etc must you cache to supply the next group?
