Question 11
A leafy tree in the center is surrounded by two bare trees and two palms.
A monkey takes:
- 3 seconds to swing between the central leafy tree and any other tree;
- 2 seconds between a bare tree and a palm;
- 7 seconds between the two bare trees or between the two palms.
Each tree bears a different label P, Q, R, S or T. The monkey visits P, Q, S, R, T, R, P in that order. Which labels could be on the central tree if the total time is as small as possible?
