My phone battery lasts for 20hours when fully charged. The duration that the battery lasts is proportional to its percentage charge. How long will the battery last if it is 30%, percent charged?

Answer:

6 hours

Step-by-step explanation: if it lasts 20 when fully charged (100%) then it will be in the form of 100%=20hrs, this would be wrong if 30 replaced 100. This means that we need to find 30% of 20 because 20 is really just 100 percent. 30% of 20 is 6 so it will last 6 hours and 00 minutes.

Must be an Iphone XD
