4 часа 30 мин=270мин
6 часов 45 мин=405мин
1/270 часть бассейна нальет первый кран за 1 мин
1/405 часть бассейна нальет второй кран за 1 мин
1/405+1/270=5/810=1/162 часть бассейна нальют 2 крана за 1 мин
1:(1/162)=162 мин - время за которое 2 крана наполнят весь бассейн
первый кран был открыт 162 мин
162/270=3/5 - бассейна наполнит первый кран за 162 мин1-3/5=2/5 бассейна нужно наполнить второму крану
2/5 : 1/405=2*405/5*1=810/5=162 мин - Через столько времени бассейн наполнится.
