When Famke charges her phone, it gains 2 percentage points each minute. When Famke uses her phone, it
loses 5 percentage points each minute.
Once. Famke used her phone for some time, and then charged it for twice the amount of time she used it.
In the end, her phone lost 10 percentage points.
How long did Famke use her phone and how long did she charge it?

let's say t is the amount of time she used it, then it lost t*(5/min) percentage points. then, she charged it for 2t, so it gained (2t)*(2/min) =t*(4/min) percentage points.

this means that above this time period, the phone lost t*(5/min)-t*(4/min) =t*(1/min) percentage points; because this loss is recognized to be 10 percentage points, this means t*(1/min) =10, so t=10 min.

famke used her phone for 10 minutes and charged it for 20 minutes.
