To find out how long it will take a phone to charge 100% if it charges 3% every 5 minutes, you have to put it in a fraction.
3/5
3 is the percent charged and 5 is the time.
You have to find out what 100 divided by 3 is. The answer is 33.3.
So,
3/5 times 33.3 is equal to 99.9/166.5.
It will take 166.5 minutes for the phone to charge to about 100%.
