RATES:
Oscar, %288%2F10%29%28lines%2Fminutes%29=4%2F5, lines%2Fminute
David, %2812%2F15%29%28lines%2Fminutes%29=%284%2F5%29%28lines%2Fminute%29


IF WORK TOGETHER,
%284%2F5%2B4%2F5%29%28lines%2Fminute%29
8%2F5lines%2Fminute


How much time for both together to write 32 lines?
32%28lines%29%285%2F8%29%28minutes%2Fline%29
