-you are standing next to a pile of Spam cans
-these are sufficient in number to complete this puzzle!
-you wish to walk a distance of 100 miles (straight path)
-you can walk 20 miles per day
-to keep up your strength, you need to eat a Spam can per mile
-you can carry 60 cans, no more

How long (minimum) will it take you to reach your destination
if you can hide cans at points 20, 40, 60 and 80 only?

Nobody likes Spam?

True... not in a can and not in your email

Perhaps you should try making it cans of spinach...

I love spam actually...and a spam sandwich is out of this world!!!

I never was any good at word problems

But will give it a shot

BRB

ouch...my head hurts and I ran out of fingers and toes

think I need to get a stock pile of 60 at mile 40 and then I can make the final 3 day trek of 60 80 100 with 60 cans...I think

Correct soot!
Hint: start by hiding 120 cans at mile 20

Well, I got 25 days, but that was needing 180 at mile 20 on day 17....

Good try Looney.

Another hint: can be done in 15 days.

Day 1 walk to 20 hide 200 (total 20)
Day 2 walk back to start
Day 3 walk to 20 hide 200 (total 40)
Day 4 walk back to start
Day 5 walk to 20 hide 20 (total 60)
Day 6 walk back to start
Day 7 walk to 20 hide 20 (total 80)
Day 8 walk back to start
Day 9 walk to 20 hide 40 (total 120)
Day 10 walk to 40 hide 20 (total 20)
Day 11 walk back to 20
Day 12 walk to 40 hide 40 (total 60)
Day 13 walk to 60 (keep 40)
Day 14 walk to 80 (keep 20)
Day 15 walk to 100 (mission complete)

GREAT solve soot!!
