The Associative Laws say that it doesn't matter how we group the numbers (i.e. which we calculate first) ... ... when we add : (a + b) + c = a + (b + c). ... or when we multiply : (a Ã b) Ã c = a Ã (b Ã c).
To complete the PCT in two months (or less) you will need to average approximately 43.6 mi / 70.2 km per day (this was my longest day on trail).
Among PCTs with the highest use, the average length of stay for these patients was 36 days. The length of stay for similar patients in the other three PCT groups was at least nine days shorter. This pattern is repeated for patients over 85.he difference in observed length of stay between those over 65 and those under 65 admitted as an emergency is also stark. In 2009/10, the average length of stay was approximately three days for patients under 65, but nine days for patients over 65.
