Question

There is a patch of lily pads on a lake. Every day, the patch doubles in size.If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?

STEP BY STEP EXPLANATION NEEDED...​

Answer 1

➝We know that the lake is entirely covered on day 48.

→So what was it the day before that?

If the lily pad patch doubles every day, the day before day 48, it was covering half the lake.

• Right?

If you double half a pie you have a whole pie.

So how long would it take for the lily pad patch to cover half of the lake?

→47 days.
