You come across a 38ft wicde canyon which is 200ft deep and it goes on for eternity. You obviously cannot walk around it but in your disposal you have a 12ft high ladder andd as much rope as you need. How do you get over the canyon?
well,
If the supply of rope is endless, you could throw the ladder into the canyon, and then fill it up with the rope and then walk across, may take a while as it would need a lot of rope though.
Tie the rope onto something and lower yourself and the ladder to the canyon floor. Then climb up the other side. The ladder? Maybe use it to climb up the first 12 feet on the other side!
