Question

if there is a swimming pool and it contains 1 litre of water , the amount of water in the pool increases to twice the previous amount every minute , and if the pool is completely filled after 60 minutes , when does the pool reaches half the amount of water? :D

Answer 1

let`s start
tell me the amount of water in the pool when time is 2min = ?
3min = ?

Answer 2

At 0 min, V = 1L
At 1 min, V = 2L
At 2 min, V = 4L = 2^2L
At 3 min, v = 8L = 2^3L
Can you see then pattern?
At 60 min, what do you get for v?



v(60) = 2^60:L
You want to find the time for half of v(60)
so this would be 2^60 / 2 = 2^59.
I'll leave the last step for you.
At what time in minutes would we get 2^59L of water?
