Question 839595
Find the rate of filling, as tankfulls per hour.
{{{1/15+1/12-1/8}}}
LCD is 2*2*2*3*5
{{{8/120+10/120-15/120}}}
{{{3/120}}}
{{{highlight_green(1/40)}}}, tanks per hour.


Uniform rate equation for filling the tank is {{{(1/40)*t=T}}}
t = time in hours
T = how many or how much tank to fill
You are interested in filling 1 tank, so T=1.
Specific equation to solve is {{{highlight((1/40)t=1)}}}; solve for t.
