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).
Detecting PCP in your system relies heavily on the type of test. 1  Urine tests can detect PCP after 4-6 hours and for up to 7-14 days. 2  Blood tests are best done within 1-4 hours since plasma levels peak during that time. 3  Hair tests can detect PCP within 5-10 days after use and for up to 90 days.
