Question 1123369
------------------------------------------------------
generator can run for 6 hours when its fuel tank is 3/5 full, how long can it run when the fuel tank is 1/2 full?
------------------------------------------------------



Assuming constant rate, rate not depending on how full,


{{{(3/5)/6=(1/2)/x}}}


{{{3/(5*6)=1/(2x)}}}


{{{1/10=1/(2x)}}}


{{{highlight(x=5)}}}-----------------five hours
