Hi, can someone please help to explain by step-by-step instructions (in detail) in the most simplest way and clear to understand. Would Greatly appreciate it.
1-
Three machine, K, M, and P, working simultaneously and independently at their respective constant rates, can complete a certain task in 24 minutes. How long does it take Machine K, working alone at its constant rate, to complete the task?
(1) machines M and P, working simultaneously and independently at their respective constant rates, can complete the task in 36 minutes.
(2) Machine K and P, working simultaneously and interdependently at their respective constant rates, can complete the ask in 48 minutes.
2-
If n and t are positive integers, is n a factor of t?
(1) n = 3^n-2
(2) t = 3^n
