Question

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 1

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.
