We will start by finding the rate per 5 seconds since the first question wants it in 45 seonds.
%285liters%2F25seconds%29=%281liter%2F5seconds%29

It is looking for the x amount of liters in 45 seconds. write the equation as 2 different rates
%28xliters%2F45seconds%29=%281liter%2F5seconds%29
cross multiply
5x=45
x=9
The first answer is 9 liters for every 45 seconds.

now we are looking for 60 liters in x amount of seconds.
%2860liters%2Fxseconds%29=%281liter%2F5seconds%29
cross multiply
300=x
The seconds answer is 300 seconds for 60 liters.
