Answer / guest

The safe must have moved 22 inches forward.

If the rollers make one revolution, the safe will move the
distance equal to the circumference of the roller. Hence,
the distance covered by the safe is

= PI * Diameter (or 2 * PI * Radius)

= PI * 7

= 3.14159265 * 7

= 21.99115

= 22 inches approx.

In the middle of the confounded desert, there is the lost city of "Ash". To reach it, I will have to travel overland by foot from the coast. On a trek like this, each person can only carry enough rations for five days and the farthest we can travel in one day is 30 miles. Also, the city is 120 miles from the starting point. What I am trying to figure out is the fewest number of persons, including myself, that I will need in our Group so that I can reach the city, stay overnight, and then return to the coast without running out of supplies. How many persons (including myself) will I need to accomplish this mission?
