47 days

If it doubles in size every day, it would take longer to cover half the lake, but less time to cover the rest of it. So is the answer 47?

But it's already covered with lake. It needs to find a new lake. 🤦🏻‍♂️

47 days for half the lake,then 1 more day to cover the other half of the lake.

Should be a group BA. My first thought was 24, then, nah - too easy. 😁

Not a riddle, a math problem...

(A1 - A1*2^48)/(1 + 2) = 1

Find out A1 and then do the same in reverse for 0.5 and replacing 48 with n
