For each subset it can either contain or not contain an element. For each element, there are 2 possibilities. Multiplying these together we get 27 or 128 subsets. For generalisation the total number of subsets of a set containing n elements is 2 to the power n.
Total time taken by Jon was 4.5 hours
Time taken by Sam was 5.5 hours
This implies that John traveled faster than Sam because he took shorter time to get to the camp, thus we conclude that from the given information, the correct answer is:
Sam and Jon traveled at the same rate of speed to camp.
